The number of hexagonal faces that are present in a truncated octahedron is

In a simple cubic unit cell,how many unit cells share each lattice point located at the corner?

$CsBr$ crystal has $bcc$ structure. It has an edge length of $4.3 \ \mathring{A}$. The shortest interionic distance between $Cs^{+}$ and $Br^{-}$ ions is ................ $\mathring{A}$.

If $AB$ crystallizes in a zinc blende structure with $B^{-}$ ions at lattice points,what fraction of tetrahedral voids is occupied by $A^{+}$ ions? (Express as a percentage)

Choose the correct statement for the given cubical structure.
