Step-by-step explanation:

Given : The volume of a cube is 512 cm cube.

To find : Its surface area?

Solution :

The volume of a cube is 512 cm cube.

The formula of volume of cube is

V=a^3V=a

3

512=a^3512=a

3

8^3=a^38

3

=a

3

a=8a=8

The side of the cube is 8 cm.

The surface area of cube is A=6a^2A=6a

2

Substitute the value of a,

A=6(8)^2A=6(8)

2

A=6\times 64A=6×64

A=384cm^2A=384cm
