The volume of atoms present in a fcc unit cell of a metal (r=atomic ra

1.	The volume of atoms present in a fcc unit cell of a metal (r=atomic radius).
Answer» `(16)/(3)pir^(3)` `(12)/(3)pir^(3)` `(24)/(3)pir^(3)` `(20)/(3)pir^(3)` Solution :(a) Total NUMBER of atoms in the UNIT cell fcc=4 Total volume of an atom `(4)/(3)pir^(3)xx4"["V=(4)/(3)pir^(3)"]"` `(16)/(3)pir^(3)`
