Step-by-step explanation:

as we just learned a few minutes ago, the volume of a prism is

base area × height

the trick is to see that this prism is laying on its side !

the base area is a triangle.

we see here, it is a right-angled triangle that is also isoceles (both legs are equally long).

so, as explained in the other answer earlier, the area of that triangle is simply

leg² / 2 = 7.5²/2 = 28.125 ft²

and the volume of the prism is

28.125 × 10 = 281.25 ft³
