d = 4 atoms x MW x 1mol/NA
(2r2)3 or use l3if they give you the edge length
d = density. Units will be g/cm3
4 atoms b/c FCC has (1/8 atom x 8 corners) + (1/2 atom x 6 faces) = 4 atoms total
MW = Molecular Weight of whatever atom it is, units are g/mol
NA = Avogadro's number = 6.022 x 1023
2r2 = edge length using radius. If they give you the edge length no need to use this just cube the length to get the volume
Body Centered Cubic (BCC)
d = 2 atoms x MW x 1mol/NA
(4r/3)3
