Find the volume of the triangular prism described below.
The base is a 45°-45°-90° triangle with a leg of 4 in. The height is 1.7 in.

A 45-45-90 triangle has two legs that are the same length. So both legs are 4 in.

Area of the triangle = 1/2 x 4x4 = 8 square in.

Volume = 8 x 1.7 = 13.6 cubic inches.

a .4y4

hope this !
