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

We know that
Volume of cube =a
3
So we get
Each edge of the cube =
3
512
=8cm
We know that
Surface area of cube =6a

By substituting the values
Surface area of cube =6×(8)
2
So we get
Surface area of cube =6×64=384 cm
2
Therefore, the surface area of cube is 384 cm
