Hello students..

In a cubic close pack structure of N atoms, mainly two kinds of interstecies are present: Octahedral and tetrahedral voids or interstecies.

The number of octahedral voids are same as the number of lattice sites and the number of tetrahedral voids are double the number of the total lattice sites.
