CALCULATOR
Volume of a Triangular Prism Calculator
Find prism volume from triangular base and extrusion length. Example: Base: 2 m, Perpendicular triangle height: 2 m, Length: 2 m gives 4 m³. Triangle height perpendicular to its base; prism length perpendicular between congruent parallel faces. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does no
Triangle height perpendicular to its base; prism length perpendicular between congruent parallel faces. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Triangular area bh/2 times perpendicular extrusion length.
Accepted inputs: Base: 0.001 to 1,000 m; Perpendicular triangle height: 0.001 to 1,000 m; Length: 0.001 to 1,000 m.
How the calculation works
V = base × triangle height × prism length /2
Worked example
With base 2 m, perpendicular triangle height 2 m, length 2 m, prism volume from triangular base and extrusion length is 4 m³.
Assumptions and limits
Triangle height perpendicular to its base; prism length perpendicular between congruent parallel faces. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Triangular area bh/2 times perpendicular extrusion length.
