10. what is the volume of the prism to the nearest whole unit?
Ainat [17]
To calculate the volume of the rectangular prism and the triangular prism you will multiply the area of the base by the height of the prism.

1.  V = BH
     V = lwH
           12 x 8 x 4
     V = 384 cubic inches

2.   V = BH
      V = 1/2bhH
            1/2 x 12 x 2 x 18
      V = 216 cubic feet
