Estimate the amount of gravel, stone, or sand needed for your project.
Common densities: Gravel (1.41), Sand (1.35), Crushed Stone (1.35)
To calculate the amount of gravel needed, multiply the length, width, and depth of the area to get the volume in cubic feet.
Formula: Length (ft) × Width (ft) × Depth (ft) = Volume (ft³)
Then divide by 27 to get Cubic Yards: Volume (ft³) / 27 = Volume (yd³)
Finally, multiply by the density (usually 1.41 tons per cubic yard for gravel) to get the weight.
