Measure each area
Break an uneven project into simple sections, then add the volumes together.
Use your length, width, and planned depth to estimate cubic yards. The final material amount still depends on the job and the layer you are building.

Enter the length and width in feet. Enter the planned depth in inches. The result is a rough cubic-yard figure, not a price or order confirmation.

Break an uneven project into simple sections, then add the volumes together.
A base, fill layer, drainage run, and finish surface may use different material.
The address, access, and placement area belong in the order discussion.
Your measurements, material, delivery address, and placement details give the conversation a useful starting point.
