Prism Volume Calculator
Calculate prism volume, base area, lateral area, and surface area from perpendicular height and triangular, square, rectangular, regular-polygon, or custom base data.
Prism volume from base area and perpendicular height
English SERP competitors usually frame prisms by base area times perpendicular height, then add triangular prism and regular-prism cases. This tool keeps base shape selection visible and includes a custom base-area mode for textbook and construction-style inputs.
B is base area and h is perpendicular height.
P is base perimeter for a right prism.
Supported base inputs
| Base mode | What to enter |
|---|---|
| Triangular prism | Three side lengths of the triangular base. |
| Square or rectangular prism | Side length, or length and width. |
| Regular polygon prism | Number of sides and side length. |
| Custom base | Known base area and perimeter in the selected units. |
