VOLUME OF A TRIANGULAR PRISM #1
______________________________________________________________________________________________
Directions: Find the volume of each right triangular prism below. First find the area of the triangular base (1/2 x base x height). Then multiply this area times the height of the prism. For example in #1, the base is 5 and the height of the triangle is 6, so ½ x 5 x 6 = 15. Then multiply this area times the height of the prism, which is 2 inches.
