The formula used to calculate the volume is:
\[ \text{Volume} = \frac{(D - 4) \times \left(\frac{D - 4}{2}\right) \times L}{8} \]
This rule appeared about the same time as the Doyle log rule, and its results are identical to those of the Doyle log rule.
Steps to calculate the volume:
Let's assume the following values:
Using the formula:
\[ \text{Volume} = \frac{(20 - 4) \times \left(\frac{20 - 4}{2}\right) \times 16}{8} = 32.0 \]
