Pyramid Volume Calculator

About this calculator

This calculator finds the volume and surface area of a square-based pyramid from its base side length and height, using volume = (1/3) × base area × height and adding up the base and the four triangular lateral faces for surface area.

It's used in geometry classes covering 3D solids, in architecture and engineering when estimating material for a pyramidal roof or structure, and in general knowledge or history contexts — like estimating the volume of stone in a monument such as the Great Pyramid of Giza from its known base and height. The 1/3 factor is the key thing students often need to check, since a pyramid holds exactly a third of the volume of a prism with the same base and height.
