How it works
The three quantities are mutually perpendicular semiaxes. Full diameters must each be halved before entry. This form solves for first semiaxis; enter the known quantities in Volume, Second semiaxis, Third semiaxis.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Volume | 100.53096491487338 cm³ | Formula symbol: V. Required unit: cm³. Must be greater than zero. |
| Second semiaxis | 3 cm | Formula symbol: b. Required unit: cm. Half the full dimension in that direction. Must be greater than zero. |
| Third semiaxis | 2 cm | Formula symbol: c. Required unit: cm. Half the full dimension in that direction. 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 first semiaxis 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.
