Find Volume of Composite Figures Practice Test

A ramp display is built from two non-overlapping right rectangular prisms. Prism A measures $9\text{ in} \times 2\text{ in} \times 2\text{ in}$. Prism B measures $9\text{ in} \times 2\text{ in} \times 1\text{ in}$. The prisms touch along a face, so the total volume equals the sum of their volumes. What is the total volume?

A composite solid is made from two non-overlapping right rectangular prisms that share the same height. Prism A is $4\text{ ft} \times 2\text{ ft} \times 3\text{ ft}$. Prism B is $2\text{ ft} \times 2\text{ ft} \times 3\text{ ft}$. They touch along a face (no overlap). The total volume equals the sum of the parts. What is the total volume of the composite solid?
