Use our free River Rock Calculator to quickly determine how many cubic yards or tons of decorative river rock you\'ll need for your landscaping project. Perfect for garden beds, pathways, and ground cover, get an accurate estimate to avoid material waste and ensure a beautiful finish.
Formula:
Volume (cubic feet) = L × W × (D / 12)
Volume (cubic yards) = Volume (cubic feet) / 27
Weight (tons) = Volume (cubic yards) × Rock Density
Where:
- L = Length of the area (in feet)
- W = Width of the area (in feet)
- D = Desired depth of river rock (in inches)
- Rock Density = Approximate density of river rock (e.g., 1.4 tons per cubic yard)
