Question

The volume of cube is 512 cm3 . Find the surface area​

Answer 1

Answer:

Volume of a cube =512 cm ³

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 ²

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 ²

Answer 2

Let each side of the cube be a cm

Then, the surface area of the cube =$(6a^2)cm^3$

$3a^2$= 512

$a^2⟹$ 8
