Use the formula for finding the volume of a rectangular prism to calculate the volume of the figure.

2.5 ft
5 ft
3.5 ft
A. 437.5 ft^3
B. 0.4375 ft^3
C. 43.75 ft^3
D. 4.375 ft^3

To find the volume of a rectangular prism, you multiply the length, width, and height. In this case, the dimensions are 2.5 ft, 5 ft, and 3.5 ft.

Volume = length x width x height
Volume = 2.5 ft x 5 ft x 3.5 ft
Volume = 43.75 ft^3

Therefore, the correct answer is C. 43.75 ft^3.
