## Volume of a triangular prism formula

The volume formula for a triangular prism is (height x base x length) / 2, as seen in the figure below: So, you need to know just three measures: height, base, and length, in order to calculate the volume.

## How to calculate the volume of a triangular prism?

You need to take or know (from a plan/schematic) three length measurements. Make sure they are all in the same length unit, or convert accordingly until they are. The result from the calculation using our volume of a triangular prism calculator is always in cubic units: in3, ft3, yd3, mm3, cm3, meters3, etc.

The math is fairly simple, so it can be done using an ordinary calculator as well as by hand, but it can be difficult with large numbers or numbers with fractions.
