Answer:
Volume of the prism = 280 ft^3
Step-by-step explanation:
Recall that the volume of a prism is given by the following formula:
Volume = B * H
where B is the area of the base (in our case a right angle triangle), and H is the prism's height (in our case 16 ft)
Then we estimate the area of the triangle at the base as base* height/2 :
Area triangle = 5 * 7 / 2 = 35/2 ft^2
and multiply by the prism's height to get its volume:
Volume = 35/2 * 16 = 280 ft^3
