Question

The volume of a cube is 512cm3 ,its total suface area is ?

Answer 1

Answer:

Volume of cube =a^3

a^3=512

a=8

Surface area =6a^2

6*8*8=384cm^2

Answer 2

Answer:

• Total surface area of cube = 384 cm²

Step-by-step explanation:

Given:

• Volume of cube = 512 cm³

To Find:

• Surface area of cube

Now, first we will find edge of cube

⇒ Volume of cube = a³

⇒ 512 = a³

⇒ a = 8 cm

Now, we will calculate TSA of cube,

⇒ TSA of cube = 6a²

⇒ TSA of cube = 6 × 8 × 8

⇒ TSA of cube = 384 cm²

Hence, Total surface area of cube = 384 cm²
