Question

A brick measures 20 cm x 10 cm x 5 cm. How many bricks will be required for a wall
of dimensions 10 mx 5 mx1m?​

Answer 1

Given:

Dimensions of brick = 20cm × 10cm × 5cm

Dimensions of wall = 10m × 5m × 1m

Now,

Volume of brick = (20×10×5)cm³

= 1000cm³

Volume of wall = (10×5×1)m³

= 50m³

= (50 ×1000000)cm³

= 50000000cm³

So,

Bricks required = 50000000cm³/1000cm³

i.e. Bricks Required = 50,000

Therefore, bricks required is 50,000.
