The space number space of space atoms space in space hpc space lattice space comma straight Y space equals space 6 Tetrahedral space voids comma space straight X space equals space 2 cross times 6 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 12 Only space 2 divided by 3 rd space space of space these space will space occupy space so comma space 12 cross times 2 over 3 equals space 8 therefore straight X equals space 8 comma space straight Y equals space 6 Formula space will space be space straight X subscript 8 straight Y subscript 6 space space ie. space straight X subscript 4 straight Y subscript 3 space end subscript

sir in types of unit cell we studied it can be of 4 types i.e primitive, face centred, body centred and end centred, but while studing 3D close packing it was told that it can be of 3 types i,e. simple(primitive) cubic unit cell, hcp and ccp. but i am not able  to understand that hcp is a type of unit cell or it is one of the 7 crystal system or somthing else?and if it is type of unit cell then why it is not taught under the topic types of unit cell. and if it is a crystal system then what about the rest 6 crystal system, then why rest 6 crystal system does not comes under 3 dimensional close packing?
