Answer:
175 ft^3
Step-by-step explanation:
The easiest way of thinking about this problem is to divide the shape into two rectangular prisms. Prism 1 has height of 7 ft, width of 3 ft, and depth of 7 ft. Prism 2 has height of 2 ft, width of 2 ft, and depth of 7 ft.
After dividing up the shape, find the volume of each prism:
Prism 1: V = l*w*h = 7*3*7 = 147 ft^3
Prism 2: V = l*w*h = 2*2*7 = 28 ft^3
The total volume is found by adding the volume of the two prisms together:
147+28 = 175 ft^3
