Yards of dirt

A 'yard' is a cubic measure of material 3 x 3 x 3 feet. Commonly used in landscaping and materials such as sands, soils and small stone delivery. A cubic yard is actually quite a lot of sand or soil - and would fill about 10-12 garden wheel barrows.

A 'yard' is also used as a common measurement of 'bucket' size of earthmovers and loaders.
