Measure the width, length and depth of the soil. Multiply these three measurements together to find the volume of the soil. For instance, if the soil measures 3 m long, 2 m wide and 0.5 m deep, multiply 3 times 2 times 1.5, to get 3 cubic metres. In imperial units, 6 feet long by 4 feet wide by 2 feet deep would mean multiplying 6 times 4 times 2 to get 48 cubic feet - the calculation is the

by cutting into or excavating an area of ground; or by constructing a new area, such as an embankment by adding earth based materials to a certain location ; When bulk earthworks are taking place, the aim is to reuse as much as possible of the excavated materials to prevent both the costly collection of waste material and the delivery of extra earth materials.

The volume of soil to be removed when excavating for a basement is actually smaller than the volume of the soil after it has been removed. This is because the untouched soil, measured in bank yards, becomes less compacted when it is disturbed. The less compacted soil occupies more space and is then measured in swelled yards.
