What to enter
| Input | Meaning and units |
|---|---|
| A1 (length^2) | Enter a1 in length^2; use the same basis as the other measurements. |
| A2 (length^2) | Enter a2 in length^2; use the same basis as the other measurements. |
| Height (length) | Enter height in length; use the same basis as the other measurements. |
Understanding your result
Read volume (length^3) in the units and model stated on this page. The formula volume=h*(A1+A2+sqrt(A1*A2))/3 defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
