About the Square Pyramid Calculator
The square pyramid calculator is a free online tool: volume, slant height and surface area. Enter base edge (a) and height (h) and the results update instantly, alongside a labelled diagram so you always know which measurement goes where.
Choose your input unit (mm, cm, m, km, in, ft or yd) and optionally show the results in a different one: lengths, areas and volumes are converted correctly. Every answer shows the formula behind it, and the calculation runs in your browser, so nothing is uploaded.
Square Pyramid Calculator example
Base edge (a) = 6 cm
Height (h) = 8 cmVolume = 96 cm³
Slant height = 8.544 cm
Lateral surface area = 102.528 cm²
Total surface area = 138.528 cm²
Base area = 36 cm²
Lateral edge = 9.0554 cmHow to use the Square Pyramid Calculator
- Pick the unit your measurements use. All dimensions must share the same unit.
- Enter base edge (a) and height (h). Focus a field to highlight the matching label on the diagram.
- Read the results as you type. The largest card is the main answer; the others are the related measurements.
- Copy a single value, copy everything, or share a link that keeps your inputs.
Square Pyramid Calculator FAQ
What formulas does the square pyramid calculator use?
V = ⅓a²h; l = √(h² + (a/2)²); Lateral SA = 2al; Total SA = a² + 2al.
Can I use different units?
Yes. Pick the input unit and, if you like, a different output unit. Area results are shown in squared units and volumes in cubed units.
Is this square pyramid calculator free and private?
Yes. It is free with no sign-up, and calculations happen on your device, so your numbers are never sent to a server.
