Question

The perimeter of one face of a cube is 40 cm. The volume of the cube is _________.

Answer 1

Let each side of the cube be a cm.

Each face of a cube is a square.

∴ Perimeter of one face of cube = 4a

⇒ 4a = 40 cm

⇒ a = 10 cm

∴ Volume of the cube = a³ = (10 cm)³ = 1000 cm³

Thus, the volume of the given cube is 1000 cm³.

The perimeter of one face of a cube is 40 cm. The volume of the cube is ___1000 cm³____.
