A cube has side length x. One side of the cube is increased by 4 inches, and another side is doubled. The volume of the new rectangular prism is 450 cubic inches. The equation 2 x cubed + 8 x squared = 450 can be used to find x. What was the side length of the original cube? Use a graphing calculator and a system of equations to find the answer.
