# Program for Volume and Surface Area of Cube

Cube is a 3-dimensional box-like figure represented in the 3-dimensional plane. Cube has 6 squared-shape equal faces. Each face meet another face at 90 degree each. Three sides of cube meet at same vertex.

Examples:

Input : Side of a cube = 2 Output : Area = 8 Total surface area = 24 Input : Side of a cube = 3 Output : Area = 27 Total surface area = 54

Volume: a*a*a

Total Surface area: 6*a*a
