Pyramid Volume Calculator
Calculate rectangular pyramid volume.
How to Use the Pyramid Volume Calculator
Enter the base dimensions and perpendicular height to calculate pyramid volume.
Practical Example
A square pyramid with a 6 × 6 base and height 9 has a volume of 108 cubic units.
Factors That Affect the Result
Use perpendicular height rather than slant height. Base area must match the actual base shape.
Frequently Asked Questions
What is the pyramid volume formula?
Volume equals one third of base area times perpendicular height.
Can I use slant height?
No, unless you first convert it to perpendicular height.
What units are returned?
Cubic units.

Calculating Pyramid Volume
Pyramid volume is one third of base area multiplied by perpendicular height: V = (1/3)Bh. The base can be square, rectangular or another polygon as long as its area is calculated correctly.
Use vertical height, not slant height, in the volume formula. Keep the base dimensions and height in the same linear unit so the result is expressed in cubic units. For real structures with hollow interiors or truncated tops, adjust the ideal pyramid calculation to match the actual geometry.
