How many bricks will be required to construct a wall 8 m long 6 m high and 22.5 cm thick if each brick measure 25 cm 11.25 cm and 6 cm?

Given:

The dimensions of the wall are 8 m long 6 m high and 22.5 cm thick.

The dimensions of the bricks are 25 cm 11.25 cm and 6 cm.
To do:

We have to find the number of bricks required to construct the wall.
Solution: 

We know that,

$1\ m=100\ cm$

This implies,

$8\ m=8\times100\ cm=800\ cm$

$6\ m=6\times100\ cm=600\ cm$

Number of bricks required to construct the wall$=$Volume of the wall $\div$ Volume of a brick

$=\frac{800\times600\times22.5}{25\times11.25\times6}$

$=\frac{32\times100\times2}{1\times1\times1}$

$=6400$

Therefore, 6400 bricks are required to construct the wall.
