How to find density of the system

Dear to all,
I want to find the density of my simulated system after simulation. I want to check the simulation is near to the real situation or not?
I use this code:

Initial configuration of an Al atoms

boundary p p p
dimension 3
units metal
atom_style atomic

#################################### BOX
region box block -10 10 -10 10 -10 10 units box
create_box 1 box

##################################### CREATE ATOMS
lattice fcc 4.05
region cube block -5 5 -5 5 -5 5 units box
create_atoms 1 region cube

##################################### MASS
mass 1 26.98
velocity all create 1 12345 mom yes rot yes dist uniform

##################################### POTENTIAL
pair_style eam/alloy
pair_coeff * * Al99.eam.alloy Al
neighbor 0.3 bin
neigh_modify delay 10 check yes

fix 1 all npt temp 298 298 10 iso 0 0 1000
thermo 2000
dump 1 all xyz 100 dump.xyz
run 50000

which command I need to use to get the density of my system after simulation.

i strongly suggest you read the documentation. this mailing list is not a free answering service.
