Answer 1

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume.

Answer 2

Density in si unit is kg/ m^3

Density in cgs unit is gm/cm^3
