Answer
The unit cell satisfies the condition of tertragonal structure.
Work Step by Step
Given that $a=0.356 nm$, $b=0.35nm$ and $c=0.45 nm$
$\alpha=\beta=\gamma=90^\circ$
In the given figure:
$a=b\ne c$
and
$\alpha=\beta=\gamma=90^\circ$
From table 3.2, it is determined that the unit cell is tertragonal.
