How many bricks each measuring 64 cm × 11.25 cm × 6 cm, will be needed to build a wall measuring 8 m × 3 m × 22.5 m?
Answer & explanation
Correct answer: option 4
We know that,
The volume of the cuboid = Length × Breadth × Height
Required number of bricks = [800 × 300 × 2250]/[64 × 11.25 × 6] [We know that, 1 m = 100 cm]
= 100/8 × 50 × 200 = 125000
