A force

\overrightarrow F = \left( {\widehat i + 2\widehat j + 3\widehat k} \right)

N acts at a point

\left( {4\widehat i + 3\widehat j - \widehat k} \right)

m. Then the magnitude of torque about the point

\left( {\widehat i + 2\widehat j + \widehat k} \right)

m will be

\sqrt x

N m. The value of x is _______.
