Change the height and dimensions of the triangular prism by dragging the orange dots. Note how the volume is calculated.
How to find the volume of a triangular prism
Recall that a
has two congruent, parallel faces called the bases of the prism.
The volume of any prism can be found by multiplying the area of one of the bases by its height.
In the case of a triangular prism, each base is a triangle.
As a formula
where a is the area of one triangular end face, and h is the height.
There are various ways to find the area of the triangle, use whichever method work with what you are given. In the above animation, the three sides are given, so here you would use Heron's Formula. But any method will do - below is a list of methods:
