# How many lattice points are there in one unit cell of each of the following lattice?Face-centred tetragonal

$\begin{array}{1 1}4\\6\\2\\9\end{array}$

Face-centered tetragonal=8(at corners)+6(at the face centre)=14
However,particles per unit cell =$8\times \large\frac{1}{8}$$+6\times \large\frac{1}{2}$
$\Rightarrow 1+3=4$
