"how much paper is needed to cover all the sides of a cube that measures 7 inches on a side?"

A cube has sides that are all the same. To find the area of one face of a cube,
take one edge of a side and square it. To find the entire surface area of
a cube, multiply the area of one face by 6, since there are six faces.

SA = 6s^2 {surface area of a cube is 6 x one side squared}
= 6(7)^2 {substituted 7, in for s, into surface area formula}
= 6(49){squared 7 to get 49}
= 294 in^2 {multiplied 6 by 49}
