## Dimensional Formula of Density

Dimensional formula for density is
$[M^1 L^{-3}]$
Where
M -> Mass
L -> Length

We would now derive this dimensional formula.

### Derivation for expression of Dimension of Density

Density is defined as the  mass per unit Volume
$\rho= \frac {mass}{Volume} = \frac {m}{V}$

Now the dimension of Mass = $[M^1]$

Now Dimension of Volume = $[L^3]$
Hence Dimension of Density is given by
$\text {Dimension of Density}= \frac {[M^1]} {[L^3]} = [M^1 L^{-3}]$
Unit of Density  is $kg/m^3$
