How to Find the Volume of a Rectangular Prism. A rectangular prism has three dimensions: length (l), width (w), and height (h). A rectangular prism has volume formula V = lwh. So, for example, if a rectangular prism has dimensions l = 12 in., w = 4 in., and h = 3 in., then V = 12 in. x 4 in. x 3 in.
Triangular Prism Volume Formula. The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the left) times the height,h.
