Answer 2

It is given that

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 .
