Given number is 336

First we factorise it

$\begin{array}{|cc|}\hline 2& 336\\ 2& 168\\ 2& 84\\ 2& 42\\ 3& 21\\ 7& 7\\ & 1\\ \hline\end{array}$

$336=\underset{\_}{2\times 2}\times \underset{\_}{2\times 2}\times \underset{\_}{3\times 7}$

Clearly, 3 and 7 do not have a pair, so it is not a perfect square.
