What is the total number of unit cells shared by each corner particle of a $bcc$ unit cell?

The number of atoms contained in one face-centred cubic $(FCC)$ unit cell of a monoatomic substance is:

In the fluorite structure,the coordination number of the $Ca^{2+}$ ion is.....

In a solid $AB$,$A$ atoms are in $ccp$ arrangement and $B$ atoms occupy all the octahedral sites. If two atoms from the opposite faces are removed,then the resultant stoichiometry of the compound is $A_{x} B_{y}$. The value of $x$ is ..... [nearest integer]

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

In $CsCl$ lattice,the coordination number of $Cs^{+}$ ion is:
