Find Volume of Composite Figures Practice Test

A composite solid is made from two non-overlapping right rectangular prisms that meet along a face. Prism A is $9\text{ in} \times 2\text{ in} \times 2\text{ in}$. Prism B is $1\text{ in} \times 2\text{ in} \times 2\text{ in}$. The seam shows the parts do not overlap, so the total volume equals the sum of the parts: $V_{\text{total}}=V_A+V_B$. What is the total volume?

A toy block is made of two non-overlapping right rectangular prisms stacked like steps (they only touch, they do not overlap). Prism A is $8\text{ cm} \times 3\text{ cm} \times 2\text{ cm}$. Prism B is $8\text{ cm} \times 3\text{ cm} \times 1\text{ cm}$. The total volume equals the sum of the volumes of Prism A and Prism B. What is the total volume of the toy block?
