Volume of HCP unit cell is:

The volume of the HCP unit cell is

What is the height of an HCP unit cell ?

If Z is the number of atoms in the unit cell of ccp lattice then number of octahedral voids in the unit cell is

Length of body diagonal in FCC unit cell is alpha Å . Distance between two octahedral voids in it is:

The number of octahedral voids in case of hcp unit cell is

If 'Z' is the number of atoms in the unit cell that represents the closet packing sequence…… ABCABC ….. The number of octahedral voids in the unit cell is equal

C represents the height of the HCP unit cell and a represents the edge length of the hexagonal surface of the HCP unit cell. What is the value of C/a ?
