    sir how can you say that a=2r,while zvalue is asked

    eduncle-logo-app

    in 7th line you have put value of r in place of a

    eduncle-logo-app

    here it is direct written but you have to do like this Z=1 for simple cubic Z=2 for bcc and Z=4 for fcc

    find density in all case you find when you put z=2 in density formula density comes around 19.74
