The formula to calculate the topdressing weight is:
\[ \text{TW} = A \times \frac{D}{12} \times 101.8 \]
Where:
Topdressing weight is the total weight of material needed to cover a given area to a specified depth. It is calculated using the formula provided, which takes into account the area to be covered and the depth of the material.
Example:
Calculation:
\[ \text{TW} = 1000 \times \frac{2}{12} \times 101.8 = 16966.67 \text{ pounds} \]
