actually the volume means the (side ) ^ 3
so, as far as fcc is concerned then
a= 2 root 2 r
so, a cube = (2 root 2 r ) ^ 3 – volume of fcc
as far as bcc is concerned then .
a = 3 / root 2 r
so a cube = (3/ root 2 r ) ^ 3 – volume of bcc .
and these ccp are under the catagory of fcc .
anathor oneis simple cubic
for that
a = 2 r
in which a is one side .
and r is the radii
