VOLUME OF A TRIANGULAR PRISM  #2--KEY
______________________________________________________________________________________________
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.
