This page examines the properties of a triangular prism. Show Triangular Prism Volume FormulaThe 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. The right hand picture illustrates the same formula. Download Article Download Article It's easy to assume that you'd calculate the volume of a triangular prism the same way you would for a pyramid. However, a triangular prism is a three-sided polyhedron with two parallel triangular bases and three rectangular faces. To calculate the volume, all you have to do is find the area of one of the triangular bases and multiply it by the height of the prism.

Thanks for submitting a tip for review!

For example, if the base is 8 and the height is 9, you would get ½ x 8 x 9 = 36. Therefore, the area is 36. Next, plug the area into the formula for finding the volume of a triangular prism, which is V = b x h, or volume equals the area of the base multiplied by the height of the prism. Now, plug the height of the prism into the formula and solve. As an example, if the area of the triangular base is 36 and the height of the prism is 16, you would get 36 x 16 = 576. Therefore, the volume of the triangular prism is 576. Write your answer in cubic units. If you want to learn how to calculate the height of a regular triangle, keep reading!
