Answer» The volume of cube and cubiod will be same. let height of cubiod be H So, volume of cube = volume of cuboid (side)³ = L × B × H (20)³ = 25 × 20 × H 8000 /500 = H So,H = 16 So, height of cuboid is 16 cm

Answer»

The volume of cube and cubiod will be same.

let height of cubiod be H

So,

volume of cube = volume of cuboid (side)³ = L × B × H (20)³ = 25 × 20 × H 8000 /500 = H So,H = 16

So, height of cuboid is 16 cm
