**Question:**

The total surface area of a cube is 96 cm2 . The volume of the cube is

(a) 8 cm3

(b) 512 cm3

(c) 64 cm3

(d) 27 cm3

**Solution:**

(c) Surface area of a cube = 96 cm2

Surface area of a cube = 6 (Side)2 = 96 => (Side)2 = 16

=> (Side) = 4 cm

[taking positive square root because side is always a positive quantity]

Volume of cube = (Side)3 = (4)3 = 64 cm3

Hence, the volume of the cube is 64 cm3.
