Formula

The Triangular Prism Volume Calculator uses the formula:

Volume = 0.5 × Triangle base × Triangle height × Prism length

Worked example

For example, with triangle base of 4 units, triangle height of 3 units and prism length of 10 units, the volume is 60.0000.

Inputs used
Triangle base 4 units
Triangle height 3 units
Prism length 10 units
Results
Volume 60.0000
Cross-section area 6.0000

Key terms explained

Volume
The amount of three-dimensional space an object occupies, measured in cubic units.
Area
The amount of two-dimensional space a shape covers, measured in square units.

Frequently asked questions

Find the triangle's area (½ × base × height), then multiply by the prism's length. A 4 × 3 triangle along a 10-unit length is 60 cubic units.

The cross-section is the triangular end face. Its area, multiplied by the length, gives the prism's volume.

No. As long as you use the perpendicular height to the chosen base, the area and volume formulas hold for any triangle.

Cubic units of whatever you entered. If the dimensions are in centimetres, the volume is in cubic centimetres.

The Triangular Prism Volume Calculator uses the formula: Volume = 0.5 × Triangle base × Triangle height × Prism length. For example, with triangle base of 4 units, triangle height of 3 units and prism length of 10 units, the volume is 60.0000.
