Question

The volume of a cube is 512 cm3.Find its surface area. Give the solution

Answer 1

volume of cube = a3 . a3=512 a= 8. no if you are asking Total surface area it will be 6a2 = 6*8*8 = 384 cm2 if curved surface area it will be 4a2 = 4*6*6= 256 cm2

Answer 2

Answer:

Surface area of the cube is 384 cm sq.

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

$V=a^3$

$512=a^3$

$8^3=a^3$

$a=8$

The side of the cube is 8 cm.

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

Substitute the value of a,

$A=6(8)^2$

$A=6\times 64$

$A=384cm^2$

Therefore, Surface area of the cube is 384 cm sq.
