$\text{8}$chloride ions at$\text{8}$corners${\text{Cs}}^{\text{+}}$cation at body centre along body diagonal there will be one${\text{Cs}}^{\text{+}}$cation and$\text{2}{\text{Cl}}^{-}$ions at ends of body diagonal.
$2{\text{r}}_{{\text{Cs}}^{+}}+2{\text{r}}_{{\text{Cl}}^{-}}=\sqrt{3}a$
$\text{a}$is edge length
