Cube with side length of 4cm

There are 6 sides in a cube, which all of them are squares. So, first, we're going to multiply the area of each side (or face):

The area of each side: 4 * 4 = 16; the area is 16 cm2 (squared centimeters)

Lastly, we're going to multiply the area of each side (16) by the number of sides a cube has (6):

6 * 16 = 96; the total surface area is 96 cm2
