the size of tetrahedral void is smaller than that of octahedral void

(B) For a tetrahedral void,the radius ratio is $\frac{r}{R} = 0.225$. For an octahedral void,the radius ratio is $\frac{r}{R} = 0.414$. Since $0.225 < 0.414$,the size of the tetrahedral void is smaller than that of the octahedral void.
