A triangular prism extends a triangle along a length: compute the triangular base area first (½ × base × height), then multiply by the prism length. Both intermediate and final values are shown.
V = (½ × b × h) × L — enter dimensions, get the result with steps.
V = (½ × b × h) × L
| Symbol | Meaning |
|---|---|
| b, h | Triangle base and height |
| L | Prism length |
Triangle base 6, height 4, length 10 → base area 12, V = 120 cubic units.
