Question

the surface of a cube is 13 1/2 cm squared. how long is one side of the cube

Answer 1

A cube has 6 sides. Divide the surface area by 6 to get the area of one side:

13 1/2 /6 = 2 1/4

The area of one side is S^2

To fins the length of the sides find the square root of the area:

Side = sqrt(2 1/4)

Side = 1 1/2 cm.
