For a cubic structure (namely FCC, BCC, or simple cubic) we can always draw a plane and predict the plane which has highest density of atoms. Is there any rule of thumb to arrive at such a plane? How can I determine the plane?
Close packed planes also typically have the highest d-spacing. So the first peak that one gets in an XRD pattern of a cubic crystal is from the plane with the highest d-spacing, which translates to close packing. This is true for pure metals in SC, FCC or BCC lattices. This may not hold true for compounds with those lattices.
You can follow following note, which may help you for understanding the things which you want.

first get the atoms per unit cell...then calculation would be easier...
