Chemistry

Calculate the ratio of the packingfactors for the following cases: 1) simple cubic to face centeredcubic. 2) simple cubic to hypothetical face centered body centeredcubic crystal (i.e. a face centered cubic with a similar atomplaced in the center 3) simple cubic to a simple hexagonal unitcell (hint: think about the hexagonal unit cell that can be made bydeforming a simple cube) 4) a simple cubic crystal that has acentral impurity atom that fills the interstitial space to a simplecubic crystal that has a central simple cubic structure in theinterstitial space.
