Question

The formula a=6s^2 will calculate the surface area of a cube. suppose you have a cube that has a surface area of 216 square inches. what is the length of each side?

Answer 1

216 = 6s^2

can be solved in the following manner.

216/6=s^2
36 = s^2
sqrt(36) = s

flip for better overview

s = 6

the length of each side is 6 inches. :)
