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?

200000 250000 67500 125000

125000

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
