1.	If Z is the number of atoms in the unitcell that represents the closest packing sequence -ABC ABC-, the number of tetrahedral voids in the unit cell is equal to
Answer» Z 2Z `Z//2` `Z//4` Solution :In a CLOSED PACKED structure (ccp or fcc and hcp) number of tetrahedral voids is double the number of ATOMS FORMING the MAIN lattice.
