The formula for the surface area of a cube is S 5 6x2

where x is the length of one side. Find the length of the

side of a cube with a surface area of 150 square inches.

If the length of a side is x, then the surface area of a face of the cube is x squared. there are six sides in a cube so 6 (x^2) would be the surface area.

6 (x^2) = 150

(x^2) = 25

x=5
