Pyramid Calculator
Pyramid: it uses volume = 1⁄3 × base area × height for the pyramid you describe. Worked through below with real figures, and the calculator repeats the working on your own inputs — free, on-device, instant.
Pyramid Calculator takes your base side and height and gives back the volume and surface area, applying standard volume and surface-area formulas. It's a quick, browser-based way to find the volume and surface area of the solid.
About this calculator
It uses volume = 1⁄3 × base area × height for the pyramid you describe. It matters whenever a shape has to be measured, cut, covered or compared and the geometry has to be right first. Worked below as A square pyramid with base side 6 and height 9: volume = ⅓ × 6² × 9 = 108 . — and the calculator on this page repeats exactly that working for your inputs, instantly, and offline after load.
How to use
- Enter the base edge length.
- Enter the vertical height of the pyramid.
- Press Calculate to measure the pyramid.
- Read the volume and base area.

Technical notes
Pyramid Calculator uses volume = 1⁄3 × base area × height for the pyramid you describe.
Results assume exact, idealised shapes; real-world measurement error is not included.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
FAQ
Which pyramid does this calculate?
It calculates a square pyramid, whose base is a square with the edge length you enter.
How is pyramid volume calculated?
Volume is one third of the base area times the height: (1/3)b²h.
Is height the slant or vertical height?
Use the vertical height, measured straight up from the base to the apex.
Does the Pyramid Calculator send my data to a server?
No. The Pyramid Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
A square pyramid with base side 6 and height 9: volume = ⅓ × 6² × 9 = 108.
