About the Triangular Prism Volume Calculator

A triangular prism's volume is the area of its triangular cross-section multiplied by how far that cross-section extends (its length). The triangle base, triangle height and prism length each have their own unit selector, and so does every result — the calculator converts everything automatically.

Formula: Volume = (½ × base × height) × length

Triangular prisms appear in roof trusses, tents, optical prisms and many structural engineering designs.
