Density - Plainview

Density is a property of materials - independent of shape or quantity. For example, a steel nail and a steel cube have different amounts of matter and therefore different masses. They also have different volumes. However, if you calculate density by dividing mass by volume, the result is the same for both the nail and the cube.
