How many tetrahedral and octahedral voids are possible if the number of close packed sphere in two layers is N Share with your friends Share 2 Shyama Charan Mandal answered this Dear Student, The number of tetrahedral voids is formed twice as the number of octahedral voids while close packing of atoms in ccp and hcp structures. Thus, if number of close packed spheres is equal to 'N'. Therefore, number of octahedral voids formed = N. And, the number of tetrahedral voids formed =2N. 12 View Full Answer
