In a hypothetical solid C atoms form CCP lattice with A atoms occupying all the tetrahedral voids and B atoms occupying all the octahedral voids. A and B atoms are of the appropriate size such that there is no distortion in the CCP lattice. Now if a plane is cut (as shown) then type of voids and their numbers which are present at the cross-section would be.
