Ashley is stacking two boxes on a shelf. The bottom box measures 6 inches long x 5 inches wide x 5 inches high. The top box is a cube with one edge measuring 4 inches. What is the volume of this stack? Explain how you found your answer

The volume of this stack is 214 cubic inches. The volume of the bottom box is equal to 150 cubic inches, because the formula for volume is length x width x height. The top box is a cube, which means all edges have an equal size. If one edge measures 4 inches, then the length, width, and height of the cube are all 4 inches. 4 x 4 x 4, or 4 to the power of 3, or 4 cubed, is equal to 64 cubic inches. 150 cubic inches added to 64 cubic inches is 214 cubic inches. The volume of the stack is equal to 214 cubic inches.
