packing fraction of a unit cell is drf...

packing fraction of a unit cell is drfined as the fraction of the total volume of the unit cell occupied by the atom(s).
`P.E=("Volume of the atoms(s) present in a unit cell")/("Volume of unit cell")=(Zxx(4)/(3)pir^(3))/(a^(3))`
and `%` of empty space = `100- P.F.xx100 `
where Z= effective number of atoms in s cube .
r= radius of a an atoms
a = edge length of the cube
`%` of empty space in body centered cubic cell unit is nearly :

A
