Triangular Prism Volume
Step-by-Step Derivation
Triangular Prism Volume Formula
V = (1 / 2)bhL
Triangular prism volume equals the area of the triangular base times the prism length. The base triangle area is one half times its base and height.
⚠Use the height perpendicular to the triangle base. All measurements must be positive and in the same unit.
How Triangular Prism Volume Works
A triangular prism has the same triangular cross section along its full length. Once the triangle area is known, multiplying by length gives the volume.
Triangle Base
The base of the triangular face.
Triangle Height
Perpendicular height of the triangle.
Prism Length
Distance between matching triangular faces.
Base Area
The first step is finding 1/2 bh.
💡 Example: For b=6, triangle height=4, and length=10, V=(1/2)(6)(4)(10)=120.

Frequently Asked Questions
What is a triangular prism volume calculator?▼
It calculates the volume of a prism with triangular bases.
What is the triangular prism volume formula?▼
The formula is V = (1/2)bhL, where b and h make the triangular base area and L is prism length.
How do I use this calculator?▼
Enter the triangle base, triangle height, and prism length, then click Calculate.
Is triangle height the same as prism length?▼
No. Triangle height belongs to the triangular face, while prism length is the distance between the two triangular bases.
Where is triangular prism volume used?▼
It is used for roof shapes, ramps, tents, packaging, and geometry homework.
