if the radius of a neutron is 1.0 x 10 minus 13cm calculate the density of a neutron in g/cm 3

What's the shape of a neutron. I suppose we are to assume it is a sphere but no one has ever seen one so who knows?
volume = (4/3)*pi*r^3
Then density = mass/volume.
Look up the mass of a neutron. You do the math.
