When finding the volume of a triangular prism, first we must find the area of the base. What is the area of the base of the triangular prism? Use the formula sheet

L=7 W=2 H=3

*prisim is a right triangle*

The formula for finding the area of a right triangle base is:

Area = 1/2 * base * height

In this case, the base is the length and width of the right triangle, so:

Area = 1/2 * 7 * 2
Area = 1/2 * 14
Area = 7

Therefore, the area of the base of the triangular prism is 7 square units.
