How do you calculate cubic yards of excavation?
How to calculate cubic yards? The formula: Number of Cubic Yards = Length (in feet) Width (in feet) Depth (in feet) ÷ 27. Simply multiply the three dimensions together to find the number of cubic feet, then divide by 27 to find the number of cubic yards.
How do I calculate basement excavation?
Establish, from the basement plans, the external depth, width and length of the finished basement. Record these as D, W and L. For example, if the depth is 10 feet, the width is 20 feet and the length is 30 feet, you would have D = 10, W = 20 and L = 30.

How do you calculate cubic feet?
How to calculate cubic feet
- From feet: length (ft) × width (ft) × height (ft) = cubic feet.
- From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet.
- From yards: length (yd) × width (yd) × height (yd) × 27 = cubic feet.
- From cm: length (cm) × width (cm) × height (cm) ÷ 28316.85 = cubic feet.
How is excavation volume measured?
To calculate the total excavated volume of a project, the entire project is divided into several horizontal layers. The area of a typical excavated cross-section in a horizontal layer is calculated and multiplied by the thickness of the layer. Thus, the excavated volume of this layer is obtained.
