Calculate conical or truncated soil stockpile volume from radius and height, estimate truckloads, or convert volume to weight by density.

Ideal circular piles only. Use vertical height and radius (half the diameter). Density and usable truck capacity must match the actual loose material and moisture condition.

Soil Stockpile Volume Formula

The following equation is used to calculate the Soil Stockpile Volume.

SSV = 1 / 3 × pi × R² × H
  • Where SSV is the soil stockpile volume (ft^3)
  • R is the radius at the base of the pile (1/2 of the width/length of base) (ft)
  • H is the height of the stockpile (ft)

A circular stockpile can be approximated as a cone. Irregular piles require a survey or a more suitable model. Choose the quantity to solve; use matching loose-volume and moisture conditions for density or truck calculations.

What is a Soil Stockpile Volume?

Definition:

A soil stockpile volume is the total volume taken up by a pile of soil.

How to Calculate Soil Stockpile Volume?

Example Problem:

The following example outlines the steps and information needed to calculate Soil Stockpile Volume.

First, determine the radius of the pile at the base. In this example, the radius is measured to be 10 ft.

Next, determine the height of the pile. In this case, the height is measured to be 5 ft.

Finally, calculate the soil stockpile volume using the formula above:

SSV = 1/3*pi*R^2*H

SSV = 1/3*3.14159*10^2*5

SSV ≈ 523.60 ft^3
