Answer:

Definition of Density:

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

Formula of Density:

density = mass / volume

Types of Density:

Density, mass per unit volume. ...

Area density or surface density, mass over a (two-dimensional) area.

Linear density, mass over a (one-dimensional) line.

Relative density or specific gravity, a measure of density in comparison to the density of something else.

Answer 2

Answer:

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... For example, the density of air is 1.2 kilograms per cubic metre.
