Question

The volume of a prism which has an altitude of 10 units and has a right triangle base with a hypotenuse of 13 units and a leg of 12 units is what?

Answer 1

First find area of base:
hypotenuse = 13
one leg = 12
other leg = √(13²-12²)=5
Area of base = 5*12/2=30 unit²

Volume of prism
=(area of base)*height/3
=?

Answer 2

I didn't see where the solid was a pyramid. Usually a prism is a right prism, so the

v = (area of base)*height
