The Trench Excavation Calculator streamlines your work by quickly calculating excavation quantity for multiple trenches, whether the cross-section is rectangular or trapezoidal.
How the Calculator Works
The calculator allows the input of multiple trenches with varying dimensions and shapes. Here’s how it works:
- Enter the Number of Trenches: Start by entering the number of trenches needed to calculate. You can easily handle multiple trenches in a single calculation.
- Choose Units: Whether you’re working with meters or feet, select the unit that suits your project needs.
- Define Trench Dimensions: For each trench, specify the length, width, and depth. If you’re working with a trapezoidal trench, you must also provide the top width. The calculator will automatically adjust the formula and display the correct calculation method based on your selected shape.
Excavation Volume Formula:
Rectangular Trenches: For rectangular cross-section, use the formula below;
V = W × D × L
Here, L = length, W = width, and D = depth of the trench.
Trapezoidal Trenches: For a trapezoidal cross-section, use the following formula:
V = ((W1+W2)/2) × D × L
Here L = length, W1= = top width, W2 = bottom width, and D = trench depth.
Instant Results
Once you’ve entered the trench dimensions, the calculator will instantly compute the volume for each trench and also calculate the total excavation volume of all trenches.

Frequently Asked Questions (FAQ)
The volume of trench excavation with a rectangular cross-section is calculated as the volume of a rectangular prism:
Volume = Length of channel × Width of channel × Depth of channel
The volume of trench excavation with a trapezoidal cross-section is calculated by finding the area of the trapezoid and multiplying it by the length of the trench.
Volume = [(Top Width + Bottom Width) / 2] × Depth × Length of trench
Here,
Top Width = width at ground level
Bottom Width = width at the base of the trench
Depth = vertical depth of trench
Enter the dimensions of each trench separately, and the calculator will automatically add the total volume.
Yes. You can enter each trench one by one, regardless of shape. For rectangular trenches, choose the rectangular option; for trapezoidal trenches, use the trapezoidal option. The calculator will sum all trench volumes and show the total excavation.
