Question: a) Show that the packing factor (APF) in space-centered cubic crystal structure (BCC) is 0.68. b) Show that the packing factor (APF) in face-centered cubic

a)

Show that the packing factor (APF) in space-centered cubic crystal structure (BCC) is 0.68.

b)

Show that the packing factor (APF) in face-centered cubic crystal structure (BCC) is 0.74.

c)

Iron has space-centered cubic crystal structure (BCC), atomic radius R = 0.124nm, atomic mass A = 55.85g/mol. Theoretically calculate the density for iron (Fe), the answer should be in g/cm3.
