Triangular Prism Volume Calculator
Find the volume of any triangular prism by entering its base dimensions and length.
What is a Triangular Prism?
A 3D polyhedron with two triangular bases.
A triangular prism is a three-dimensional shape with two identical triangular bases and three rectangular sides connecting the corresponding sides of the two bases.
How to Find Triangular Prism Volume
Follow these steps to find the volume.
Triangular Prism Volume Formula
The equation for a triangular prism.
Where 'b' is the triangle base, 'h' is the triangle height, and 'l' is the length of the prism.

Frequently Asked Questions
What if my triangle is a right triangle?
You still use the same formula. The base and height of the right triangle are just its two perpendicular legs.
Is the height of the triangle the same as the length of the prism?
No, the height of the triangle is a 2D measurement of the base, while the length of the prism is the 3D distance between the two triangular bases.
Can I use the side lengths of the triangle instead?
If you know the three side lengths instead of base and height, you can use Heron's formula to find the base area first, then multiply by the prism length.
Does it matter which triangular face is considered the base?
A triangular prism only has two triangular faces, and they are identical. Either one can be considered the base.
