Expert Answer

Dimensions of the brick are,

Length (l) = 20 cm, breadth (b) = 5 cm and height(h) = 5 cm

Volume of brick (V) = = 500 cm3

Dimensions of the wall are

Length (l) = 2.5 m = 250 cm,

breadth (b) = 0.5 m = 50 cm and height (h) = 5 m = 500 cm

Volume of the wall(V1) == 6250000 cm3

Let N number be the number of bricks required to make the wall.

Then, N × V =  V1

N =

12500 bricks are required to make the wall.
