How to use the pyramid volume calculator
Compute volume and slant height of a square pyramid. Enter base edge, height in the fields above; the volume, slant height, surface area are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- a — Base edge
- h — Height
Worked example
With base edge = 10, height = 12, the calculator gives volume ≈ 400; slant height ≈ 13; surface area ≈ 360.
Frequently asked questions
What is the formula for the pyramid volume calculation?
Volume = a × a × h / 3. Slant height = √(h × h+(a / 2)^2). Surface area = a × a+2 × a × [Slant height]. Here a is base edge, h is height.
What inputs do I need for the pyramid volume calculator?
You need base edge, height. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
