The formula to calculate the gravel weight (GW) is:
\[ GW = GA \cdot \frac{GD}{12} \cdot 106.1275 \]
Where:
Let's say the gravel area (GA) is 100 ft² and the gravel depth (GD) is 6 inches. Using the formula:
\[ GW = 100 \cdot \frac{6}{12} \cdot 106.1275 \]
We get:
\[ GW = 100 \cdot 0.5 \cdot 106.1275 = 5306.38 \, \text{pounds} \]
So, the gravel weight is approximately 5306.38 pounds.
