Density is usually denoted by "ρ".

Density = Mass / Volume

The si unit of mass is kg
And SI Unit of volume is m³.
Hence , SI unit of density is ---->

===== > kg/m³

======================
Volume is the amount of space occupied by a substance[liquid, solid or gas ] .
SI unit is m³.

Answer 2

1:-THE MASS PER UNIT VOLUME OF A SUBSTANCE IS CALLED DENSITY

Density = mass /volume

The SI unit of density is km/m^3

2:- the volume means of definite shape Solid
