Density is a mass of a volume unit. A unit of density is defined as a unit of mass divided by unit of volume. In its turn a unit of volume is a third degree of a unit of length. Mass and length units are main units. So density is a derived ...

Van Buchem patients had increased metacarpal outer diameter, inner diameter, cortical thickness, and bone mineral density. Calculated bone volume and derived polar moment of inertia were markedly elevated (elevations of 158 ± 33% and 497 ± 95%, respectively) consistent with increased bone strength.

The box that has more balls has more mass per unit of volume. This property of matter is called density. The density of a material helps to distinguish it from other materials. Since mass is usually expressed in grams and volume in cubic centimeters, density is expressed in grams/cubic centimeter.
