Question

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

a) 8 cu.cm b) 512 cu.cm c) 64 cu.cm d)27 cu.cm​

Answer 1

Answer:

*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
