Apply Volume Formulas to Prisms Practice Test

A right rectangular prism has length 9 units, width 2 units, and height 5 units. The base is the 9-by-2 rectangle, and the height is 5 units. Packing 1-unit cubes makes layers, and each layer has the same number of cubes as the base area. How does the base area help find the volume?
