Question

The side of a cube measures 3 cm .What will be the volume and surface area of the cube?

Answer 1

Answer :

Volume = 27 cm³

Surface area = 54 cm²

Step-by-step explanation :

Here, we will use two different rules ;

Volume of cube = ( side )³

Surface area of cube = 6 ( side )²

Let the side of the cube be  3 cm.

Side = a = 3 cm

Volume of cube = a³

                          = 3 * 3 * 3

                          = 27 cm³

Surface area of cube = 6 a²

                                   = 6 * 3 * 3

                                   = 6 * 9

                                  = 54 cm²

Hence,

The volume of cube = 27 cm³

And, surface area of cube = 54 cm²
