What is the volume of a triangular prism that is 40 feet length by 14 feet wide by 24 feet high?

The formula for the volume of a prism is cross-sectional area x length.The cross-sectional area for a triangular prism is the area of the triangle with base (width) 14 ft and height 24 feet. This area is 0.5*14*24 = sq feet.

So the volume is 0.5*14*24*40 cubic feet = 6720 cubic feet.
