Cubic Yards
A cubic yard is an imperial volume unit equivalent to the volume of a cube with sides that are one yard in length. It is normally found in the United States for measuring large volumes of materials such as soil, gravel, or concrete.
When converting volume measurements, be sure to remember that the dimensions are cubed and so doubling the sides of a cube will increase the volume by a factor of eight.
