Bank Cubic Yards from Area Measurement

Bank Cubic Yards
Truck Cubic Yards
Estimated Tonnage

Calculating the volume of material to be hauled off from a site is a fairly straight forward endeavor.
The Area (square feet) and Depth (inches) give you the volume to be removed.
First we need to convert the depth into feet:
Depth(feet) = Depth (inches) / 12
Then we need to convert Area and Depth into a volume (cubic feet):
volume (cubic feet) = Area (square feet) * Depth (feet)
After this we need to convert the volume into Bank Cubic yards (BCY):
BCY = Volume / 27
To get your Truck cubic yards, you then need to multiply your BCY by
a swell factor which for this calculator is 1.3 (if you have 100 bank cubic yards
to excavate you will haul have to haul off 130 truck cubic yards).
Finally the tonnage is then calculated off of the average weight of the material (ton/cubic yard):
Tonnage = Weight * BCY.
