Step-by-step explanation:
length of brick = 20 cm
breadth = 16 cm
height = 8 cm
volume of a brick = 20*16*8 = 2560 cm^3
length of the wall = 10 m = 100 cm
breadth = 64 cm
height = 5 cm
volume of the wall = 100*64*5 = 32000 cm^3
Therefore number of bricks required = volume of the wall / volume of a brick
= 32000 / 2560
= 12.5
