In a crystalline solid, anions Y are arranged in ccp arrangement. Cations X are equally distributed between tetrahedral and octahedral voids. If all the octahedral voids are occupied. What is the formula of the solid?

Amorphous solids are

In a solid, oxide ions are arrnged in ccp, cations A occupy A occupy (1/8)^th of the tetrahedral voids and cation B occupy (1/4)^(th) of the octahedral voids. The formula of the compound is:
