To calculate the amount of river rock needed, follow these steps:

Measure the Area: Determine the length, width, and desired depth of the area you want to cover with river rock. Ensure all measurements are in the same units (e.g., feet).
Calculate the Volume: Multiply the length, width, and depth to find the volume in cubic feet.
Convert to Cubic Yards: Divide the volume in cubic feet by 27 (since there are 27 cubic feet in a cubic yard) to get the volume in cubic yards.
Account for Waste: Add an extra 5-10% to account for settling and potential waste.

Formula:

Volume (cubic yards) = (Length (ft) x Width (ft) x Depth (ft)) / 27

For example, if you have an area that is 10 feet long, 5 feet wide, and you want a depth of 3 inches (0.25 feet):

Volume = (10 ft x 5 ft x 0.25 ft) / 27
Volume = 1.25 / 27
Volume ≈ 0.46 cubic yards

Therefore, you would need approximately 0.46 cubic yards of river rock. Don’t forget to check out rockscapes.net for an easy-to-use calculator.
