Answer: 381 m³
Explanation:
First, we will solve for the volume of the rectangular prism.
V = L * W * H
V = 16 m * 7 m * 3 m
V = 336 m³
Next, we will solve for the volume of the triangular prism. The area of the triangular base is (B * H) / 2 = (3 * 5) / 2 = 7.5
V = B * h
V = 7.5 m * 6 m
V = 45 m³
Lastly, we will add them together.
336 m³ + 45 m³ = 381 m³
