Answer 2

Answer:

6400 bricks will be required to make wall.

Step-by-step explanation:

Given : Dimension of wall is 8m long, 6m high and 22.5cm thick. if each brick measures 25cm × 11.25 × 6cm.

To find: How many bricks will be required to make wall?

Solution :

Length of the wall $8\times 100=800 cm$

Height of the wall $6\times 100=600 cm$

Thickness of the wall is 22.5 cm.

Volume of the wall $V=LBH$

$V=800\times 600\times 22.5$

Brick measures 25cm × 11.25 × 6cm

Volume of the brick $v=lbh$

$v=25\times 11.25\times 6$

Number of bricks required is the volume of wall divided by volume of bricks.

$N=\frac{V}{v}$

$N=\frac{800\times 600\times 22.5}{25\times 11.25\times 6}$

$N=6400$

Therefore, 6400 bricks will be required to make wall.
