Question

How many bricks each size 25cm×13.5cm×6cm will be required to built a wall 8m long 5.4m high and 33cm thick?

Answer 1

We would be using the concept of Volume to solve this question.

Firstly, convert the dimension of the wall into 'cm':-

It would become 800cm, 540cm and 33cm

Now, find the volume of the both wall and brick:-

As we know that the volume of a cuboid is lbh. So, we substitute the values.

Wall:-

Volume = lbh

= 800 x 540 x 33

= 14256000 cm³

Brick:-

Volume = lbh

= 25 x 13.5 x 6

= 2025 cm³

Now, to find the number of bricks. Divide the volume of wall by the volume of a brick.

Number of Bricks = $\frac{14256000}{2025}$

= 7040

So, we would require 7040 bricks to build the wall !

Answer 2

HELLO DEA FRIEND.....!!!!!!!!

HERE IS UR SOLUTION...

I,E. NO OF BRICKS NEEDED R = VOLUME OF WALL÷ VOLUME OF BRICK...

=> 800×540×33. (changing it into CM)...
=> 14256000 cm ^3......

VOLUME OF BRICK = 25×6×13.5
=2025....

BRICKS NEEDED R..=14256000÷2025
=7040

HOPE IT VLL HELP UH. ....
