3. How Do You Calculate the Amount of River Rock Needed for a Project?
To calculate the amount of river rock needed, determine the area you want to cover and the desired depth. Use the formula: Volume (cubic feet) = Area (square feet) × Depth (feet). Convert the volume to tons, considering that one ton of river rock typically covers about 80-100 square feet at a depth of 2 inches. Accurate measurements and calculations are crucial to avoid over or under ordering.
3.1. Step-by-Step Calculation Guide
-
Measure the Area: Determine the length and width of the area you plan to cover with river rock.
-
Calculate the Square Footage: Multiply the length by the width to get the square footage of the area.
-
Determine the Desired Depth: Decide how deep you want the river rock layer to be, usually between 2 to 3 inches.
-
Convert Depth to Feet: Convert the depth from inches to feet by dividing by 12 (e.g., 2 inches = 2/12 = 0.167 feet).
-
Calculate the Volume: Multiply the square footage by the depth in feet to get the volume in cubic feet.
-
Convert Volume to Tons: Divide the volume in cubic feet by the coverage rate of river rock (typically 80-100 square feet per ton at 2 inches depth) to get the tons needed.
Formula:
- Area (square feet) = Length (feet) × Width (feet)
- Volume (cubic feet) = Area (square feet) × Depth (feet)
- Tons of River Rock = Volume (cubic feet) ÷ Coverage Rate (cubic feet per ton)
Example:
- Area to cover: 20 feet long × 10 feet wide = 200 square feet
- Desired depth: 2 inches (0.167 feet)
- Volume: 200 square feet × 0.167 feet = 33.4 cubic feet
- Tons needed: 33.4 cubic feet ÷ (80 square feet/ton) = 0.42 tons (approximately)
