How to Find the Volume of a Right Triangular Prism

A right triangular prism is a 3-dimensional geometric shape that has two triangles with 90-degree angles connected by three rectangles. A real world example of a right triangular prism would be a traditional camping tent. The parts of the prism include its base, which is the triangle's horizontal measurement, its height, which is the triangle's vertical side measurement, and its length, which is the measure of distance between the two triangles. You can find the volume of the prism using these three measurements.

Instructions

1. Multiply the length of the triangle's base by its height. For example, if the base is 6 and the height is 9, multiplying them together would yield 54.

2. Multiply that number by the length. For example, the length of the prism is 8, so multiplying it with 54 would result in 432.

3. Divide that number by 2 to obtain the prism's volume. For the example, dividing 432 by 2 yields 216. The volume is measured in cubic units, so if you were working with inches, the answer would be in cubic inches.
