How to Use this Rock Coverage Calculator

To use this calculator, simply enter the length and width of the area you want to cover with rocks in feet. Then, enter the depth of the coverage in inches and the density of the rock in lbs/ft³. Click the “Calculate” button to get the total weight of the rocks needed.

Explanation of the Calculation:

  • Length: The length of the area in feet.
  • Width: The width of the area in feet.
  • Depth: The depth of the rock coverage in inches.
  • Density: The density of the rock in lbs/ft³.

The formula used to calculate the total weight is:

(Length * Width * (Depth / 12) * Density)

This will give you the weight in pounds of the rocks needed to cover the specified area.
