This tool will calculate the amount of river rock you need for your landscaping project.
How to Use the River Rock Calculator
To determine how much river rock you need, follow these steps:
- Measure the length and width of the area you want to cover with river rock. Enter these values in feet.
- Measure the depth of the river rock layer you want to achieve. Enter this value in inches.
- Click the “Calculate” button to get the total weight of river rock you need in pounds.
How It Calculates
This calculator uses the following formula to calculate the total weight of river rock needed:
- Volume (in cubic feet) = Length (ft) * Width (ft) * Depth (inches) / 12
- Total Weight (in pounds) = Volume (cubic feet) * Average Weight of River Rock (100 pounds per cubic foot)
Limitations
Please note the following limitations of this calculator:
- The calculator assumes a uniform coverage area and does not account for any variations in depth or density of the river rock.
- This calculator uses an average weight for river rock, and the actual weight may vary depending on the specific type of rock you use.
- The precision of your measurements can affect the accuracy of the result. Always double-check your measurements for better accuracy.
