Question

How many bricks of size 6 cm by 4 cm are required to make a wall of size 16 m by 12 m?​

Answer 1

Area of brick = 6 * 4 = 24 cm^2

Area of wall = (16*100) * (12*100)

= 1600 * 1200 = 1920000 cm^2

Number of bricks required = area of wall/ area of brick

$= \frac{1920000}{24}$

$= 80000$

Hence, 80000 bricks are required to construct the wall.

Answer 2
