Answer 1

Answer 2

That shape is called a "prism," I think.

If you were to find the AREA of the end, and then multiply that AREA by the LENGTH of the prism (15 "), you'd have the volume.

Note that the area of the end (face) is that of a triangle and that the formula for the area of a triangle is

(1/2)(base)(height).

good luck!
