13 The volume of cube whose
*
side is e side is 8 m,​

Answer 1

Question :

Find the volume of a cube whose side is 8 m.

Given :

• Side of a cube is 8 m.

To Find :

• The volume of cube.

★ Solution :

As we know that, volume of a cube = a³

Inserting values in the equation,

⇒ Volume of a cube = a³

⇒ Volume of a cube = 8³

⇒ Volume of a cube = 8 × 8 × 8

⇒ Volume of a cube = 512 m³

Therefore, volume of a cube is 512 m³.

Knowledge cell :
