Math

Right Rectangular Pyramid: calculate results from explicit inputs, with a formula and worked example.

Formula

V = lwh/3; surface = lw + l√(h²+w²/4) + w√(h²+l²/4)

Example Calculation

Example inputs
  • Base length: 6 units
  • Base width: 4 units
  • Perpendicular height: 3 units

A centered apex above a 6 × 4 base at height 3 gives volume 24.

Frequently asked questions

How do I use this calculator?

Enter base length, base width, perpendicular height. The result updates automatically. Use Reset to restore the example values.

What method does it use?

V = lwh/3; surface = lw + l√(h²+w²/4) + w√(h²+l²/4). Euclidean geometry. Use one consistent length unit; areas and volumes use its square and cube. Degenerate shapes are rejected. Very thin shapes may lose floating-point precision.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
