Pyramid Volume Calculator

About this calculator

The volume of any pyramid — regardless of whether its base is a triangle, rectangle, or any other polygon — follows one universal formula: V = (1/3) × base area × height, where the height is the perpendicular distance from the base plane to the apex. This calculator lets you pick a base shape (rectangular, triangular, or a directly entered base area), enter its dimensions and the pyramid's height, and returns the volume without you needing to derive the base-area formula separately for each shape.

This one-third relationship — a pyramid holds exactly a third of the volume of a prism with the same base and height — is a foundational result in solid geometry that architecture and engineering students, surveyors calculating stockpile or excavation volumes, and hobbyists designing 3D-printed or scale models apply directly, since real structures from Egyptian pyramids to modern roof trusses and hoppers reduce to this same shape.
