Explanation:

Step1: Calculate volume of top prism

Volume = $8 \times 1 \times 3 = 24$ cubic feet

Step2: Calculate volume of middle prism

First find length: $8 - 1 = 7$ ft.
Volume = $7 \times 2 \times 1 = 14$ cubic feet

Step3: Calculate volume of bottom prism

First find length: $7 - 4 = 3$ ft.
Volume = $3 \times 1 \times 3 = 9$ cubic feet

Step4: Sum all prism volumes

Total Volume = $24 + 14 + 9$

Answer:

47 cubic feet
