Mass and volume.
Density
It is called the specific gravity.
Specific Gravity.
Density is the ratio of mass to volume.
Density is the ratio of the mass of a substance to the volume of the substance.

Density
That is called specific gravity
The density is the ratio between the mass and the volume of a material; an object float when this density is lower that the density of the liquid.
Density is defined by an object's mass divided by it's volume.
Density
Density is the ratio of an object's mass to its volume.
Density is the ratio of mass to volume. Thus, the density of an object is the mass of the object divided by its volume.

Relative density is determined by the ratio of the density of a substance to the density of a reference substance.
An object's density is the ratio of its mass to its volume. A very dense object has tightly packed, or compact, matter.
That's the object's density.
