hey guys welcome to a civil engineers in this video I am going to teach you how

to calculate the number of bricks required in one cubic meter of brickwork

for different sizes of bricks so let's get started I have divided this

calculation into two cases in case one I have calculated the number of bricks for

modular size update and in case two I have calculated the number of bricks

required for non-modular bricks so here is the assumption of case one size of

brick case 190 mm by 90 mm by 90 mm which is standard size of brick in India

thickness of motor equals 10 mm which is equals to one centimeter and the

volume of brickwork is 1 cubic meter to calculate the number of bricks you need

to remember a simple formula that is number of bricks equals to volume of

brickwork divided by volume of one brick with motor volume of one brick with

motor is also known as nominal side and the nominal size of Indian brick is

200 mm x100 mm x 100 mm and if you multiply this values then you will get

it as zero point zero zero two cubic meter here value is in meter not in mm

okay so don't get confused now we know volume of brick work and we know volume

of one brick with motor i.e., volume of nominal brick so substitute these two

values in this formula then we'll get the number of bricks therefore number of

bricks equals to one divided by zero point zero zero two which is equal to

500 numbers let's say the percentage of wastage at the site is 10 percent then

number of bricks including wastage equals to 100 plus 50 this 50 is 10

percentage of 500 and if we add these two value then we'll get it as 550

numbers so if the size of brick is 190mm x 90 mmx 90 mm

then you need 500 number of bricks now let's see how many non modular bricks

are required for one cubic meter of brickwork here's the assumption for case

two i.e., size of brick goes to 230 mm x 110 mm x 110 mm thickness of motor and

the volume of brickwork will remain same that is thickness of motor equals to 10

mm and the volume of brickwork equals to 1 cubic meter and we already knew this

formula that is number of bricks equals to volume of brickwork divided by volume

of one brick with motor just add thickness of motor to the size of brick

then you will get the nominal size of brick and volume of one brick with motor

equals to zero point 2 4 multiplied by zero point 1 2 multiplied by zero point

1 2 which is equals to zero point zero zero three four five six cubic meter now

we know volume of one brick with motor and volume of brickwork so just

substitute these two values in this formula to get the number of bricks

which is equals to two hundred and eighty nine point three five two numbers

now let's consider the wastage percentage as ten percent then number of

bricks including wastage equals to two hundred and eighty nine point three five

two plus twenty eight point nine three five which is equals to 318 point two

eight seven numbers now let us take the size of Rakesh 230 mm x 110 mm x 75 mm

which is also a non modular therefore volume up with Mortar equals to

point two four multiplied by point one two multiplied by point zero point zero

eight five which is equals to zero point zero zero two number 48 cubic meter

therefore number of bricks equals to 1 cubic meter divided by zero point zero

zero two double for a cubic meter which is equal to 408 point four nine six

numbers consider the wastage percentage asked

% then the number of bricks including wished is equals to four hundred and

forty nine point three four six members every country has their own sand the

size of brick India uses 190 mm by 90 mm by 90 mm and a chalet uses 230 mm by one

110 mm by 76 mm the United States uses 194 mm by 92 mm by 57 mm and United

Kingdom's uses 215 mm by 102 a member 65 mm like this every country has

their own standard the size of brick so I have calculated number of bricks

required per cubic meter for few countries okay. so let's have a look for

Australia we need 520 number of bricks per cubic meter

and for Denmark we need 537 number of pigs per cubic meter and for Germany 510

for Romania 573 for Russia 513 for South Africa 582 for Sweden 600 for UK 698 for

United State 983 so that's all for today if this video is helpful for you then

HOW MANY HOURS SHOULD I WORK? - Duration: 5:38.

- Hey friends, Dave Burkus here.

Welcome back to the DailyBurk.

Today we are answering the question:

How many hours a week should you work?

Or how many hours a day should you work?

And if...

This is a really, kind of timely topic.

In the past couple of weeks there have been stories

from superstar of CEOs boasting

about how all of their people

are expected to work 80 to 100 hours a week,

because they're trying to change the world.

And then other books coming out from CEOs

who are notable for pushing their people

to work less hours every single week.

And it begs this actual question.

Like how did the standard become 40?

And what should the right standard be?

Well how the standard became 40

was actually relatively easy.

There's a couple of different stories

about Henry Ford and whomever,

but really it was labor laws from the late 1930s in the U.S.

that really established 40 hours a week

as a regular, reasonable period of time.

Now what do we know about that period of time?

When we think about it what do we know?

Well we know that was a time where people

were working 12, 14 hour shifts in factories.

Where children were working in factories,

where women and

I mean everybody was trying to work.

Trying to beat their way out of poverty and the Depression.

There were factories taking advantage of it.

And so somebody had to come in and go,

"Whoo, okay.

"What is the reasonable amount of time we could expect,

"like, the human body to do industrial level work.

"And beyond that is reasonable.

"And while we're making those laws,

"let's make some ones for the kids, too

"because this is just disgusting."

So that was the period of time that we sort of convalesced

around this idea of 40 hours a week.

And fast forward almost 100 years,

the nature of work has changed dramatically

to where people are doing

what Peter Drucker would call knowledge work,

what I would actually call creative work.

Most people in the economy in North America,

but in really any developed country

are doing work that involves solving problems,

figuring out systems

that involves creativity among all else.

And so...

we should be thinking, okay, it's a different type of work

let's re-evaluate this.

Now two studies kind of come to mind

when I think about this.

The first is that one thing that we know

from a myriad of research

is that when it comes to this creative work,

more hours does not necessarily mean better.

And in fact one of my favorite studies

comes from a group of researchers

led by one from Stanford University

that showed that after about 55 hours a week,

any increase was actually sort of a decrease in production.

Where people who were working 70 hours a week

were just as effective as people

who were working 55 hours a week.

Which kind of makes you think about these people

boasting about 80 to 100 hour weeks.

Well, you're actually only doing as much

as any human is capable of doing in like 50 to 55 hours.

So it's great that you're wasting time at the office and all

but you're not really getting work that creates value done.

Now another line of research suggests that we're...

Again we're talking about creative work,

we're talking about knowledge work,

that people can kind of work in bursts,

with deep focus in this creative task for about 90 minutes

and then they need to take a break.

So you start doing the math,

okay 90 minutes,

then a little break maybe 30 minutes,

maybe an hour meeting et cetera.

And really if you think about how many cycles of that

could you get through in a day,

yeah, you could get through four,

but you probably couldn't.

Right?

Because you're gonna have meetings,

you're gonna have lunch breaks,

you'll have client calls, et cetera.

So really I think you shoot for two to three

of those deep work cycles for about 90 minutes per day,

and then you can kind of fill the rest of the day

with whatever meetings or calls that you have.

We're honestly talking about six or seven hours

of really productive, effective time every single day.

If you're expected to be at the office for eight hours

because we've inherited all of those things from the 1930s,

then I totally get it.

But know that like, unless you're doing

that deep focused 90 minutes spurts,

you're probably not gonna be all that effective.

What does this mean in terms of the overall week?

Well, we're looking at something that looks

a lot less than 40 hours a week.

We're looking at maybe 35, maybe 32, maybe even 30 hours.

And suddenly these companies that are actually boasting

about how their people actually work

Monday through Thursday or what have you,

start to look a whole lot more reasonable.

We need to separate out this idea

that in a knowledge or creative work economy,

presence equals productivity.

It just doesn't.

Understand how you work,

for how long of a period of time do you need focus,

which is probably gonna be 60 to 90 minutes.

Get as many repetitions of that in a day

as you can that's reasonable.

But recognize that

that's really probably gonna be two or three,

and then after that any additional time

is not actually all that productive.

Don't boast about how many hours

of work a week that you work

because we know that if it's more than 55

you're ineffective.

Honestly, start boasting about how much value you create

in the short amount of time that you work

and I think things'll go much better for you,

for your sanity.

But I think people are gonna begin to appreciate that.

Who can create the most amount of value

with the shortest period of time.

That,

not the number of hours a week that you're putting in

is gonna be the new thing to brag about

in the next five, 10, 15 years.
