Let's look at the geometric characteristics of a prism, but first please review the definition of Volume Of Three-Dimensional Shapes.

- A prism is a two dimensional triangle with height; with height it becomes a three dimensional shape.
- The trick to determining the volume of a prism to identify the type of triangle in the Base: Acute Triangle Area, Obtuse Triangle Area, Equilateral Triangle Area, Isosceles Triangle Area, Right Triangle Area, and Scalene Triangle Area. Once you know the type of triangle, compute its area and multiply it by the Prism height. You now have the volume of the prism.
- Special note, the base and height must be greater than zero.

**Volume Of A Prism Formula**

Formula = (Base area) × Height =

Formula = B × H
