Primary Mathematical Formula
Frequently Asked Questions
How do I calculate the volume of a pyramid?
Multiply the area of the pyramid’s base by its perpendicular height, then divide the result by 3. The formula is $V = \frac{1}{3} B h$, where $B$ is the base area and $h$ is the vertical height.
What is the formula for the volume of a pyramid?
The volume formula is $V = \frac{1}{3} B h$. You need the base area and perpendicular height to calculate the volume.
How do I use a pyramid volume calculator?
Enter the base area and vertical height in the appropriate fields, select your units, and calculate the result. If your pyramid has a specific base shape, use our Square Pyramid or Triangular Pyramid calculators for a more direct calculation.
Can I calculate pyramid volume using base length and height?
Yes. If you know the base dimensions, calculate the base area first. For a square base, multiply the side length by itself; for a rectangular base, multiply the length by the width. Then multiply the base area by the height and divide by 3.
Does pyramid height mean slant height?
No. The volume formula uses perpendicular height, measured at a right angle from the base to the apex. Slant height runs along a sloping face. See our Slant Height Calculator to convert between them.
What units are used to measure pyramid volume?
Pyramid volume is expressed in cubic units, such as $\text{cm}^3$, $\text{m}^3$, $\text{in}^3$, or $\text{ft}^3$. Use consistent units for all dimensions.
Why is the volume of a pyramid divided by 3?
A pyramid with a given base area and perpendicular height has exactly one-third the volume of a prism with the same base area and height. See our Why 1/3 Proof page for cube dissection and calculus derivations.
Can this calculator find the volume of any pyramid?
Yes, the general formula $V = \frac{1}{3} B h$ applies to pyramids of all base shapes. You must know the base area and perpendicular height, or have enough dimensions to calculate the base area.
