Matter: Mass, Volume and Density
All objects are made up of matter. As a consequence of this, they have mass, occupy a certain volume and have a certain density. Mass, volume and density are magnitudes. This means they have values which can be measured in units. Density is the relationship between the mass of a body and the volume it occupies. Different substances have different densities. For example, lead is denser than wood. [...]

2.1. Mass. Units of mass Mass is the amount of matter that makes up a body or object. The SI unit of mass is the kilogram (kg). Multiples and submultiples To measure different quantities, multiples and submultiples of a unit are used. [...]
-
3.1. Length The length of an object is the measurement along a certain dimension (usually the longest). The unit of length in the International System of Units (SI) is the metre (m). [...]
-
4.1. Volume The volume (V) of a body refers to the three dimensions of space occupied by the body. These are height, width and length. Since volume is related to three lengths, it is expressed in units of cubed length: m3, and cm3. [...]
