I have a cube and I know the linear density of particles along each axis (I mean- the number of particles per unit length along each axis). How can I get the volumetric density?

In cartesian coordinates just take a volume element as dV = dxdydz. The volumetric density is determined by multiplying the linear densities by each other. This gives you the volumetric density as # of particles/m^3
