The surface area Sof a cube is equal to the sum of the areas of the 6 square faces
that form the cube. We want to paint the cube and need to know how many square
units of paint to purchase. If each face has side length s, then the formula
S = 6s can be used to find the surface area of the cube. The length of a side
is indicated in the cube belowl s = x - 5). The surface area of the cube is
1944 units2.
