How it works
Lateral area sums the four congruent triangular faces and excludes the square base. Vertical and face slant heights are different quantities. This form solves for base side; enter the known quantities in Lateral area, Height.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Lateral area | 40 cm² | Formula symbol: L. Required unit: cm². Must be greater than zero. |
| Height | 4.58257569495584 cm | Formula symbol: h. Required unit: cm. Must be greater than zero. |

Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the base side result?
Lengths use cm, areas cm² and volumes cm³ on one consistent scale. The positive real branch is selected; the supplied quantities must describe the stated shape.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
