Formula Reference
All pyramid types share the same core formula:
V = (1/3) × Base Area × Height
The pyramid volume calculator computes the volume of any pyramid using the universal formula V = ⅓ × base area × height. Whether your pyramid has a square, rectangular, triangular, or regular polygon base — or you already know the base area — enter your dimensions, choose your unit, and get an instant result with conversions to cubic metres, cubic feet, litres, and more.
All pyramids share the same formula: V = (1/3) × Base Area × Height. The base area depends on the shape — for a square base it is s², for a rectangle it is l × w, and for a regular n-sided polygon it is (n × s²) / (4 × tan(π/n)).
Yes. Select the 'Triangular' base type, enter the base length and the perpendicular height of the triangular face, and the tool computes the base area as ½ × b × h before applying the pyramid volume formula.
Absolutely. Choose 'Known Base Area' mode and type the area in the selected length-unit squared. This is useful when the base is an irregular shape and you have calculated the area separately.
Use the 'Result Unit' dropdown to select any of the eight supported volume units — m³, cm³, mm³, ft³, in³, yd³, litres, or millilitres. The conversion table at the bottom shows all units simultaneously.
