A force $\displaystyle \vec{F}=(\hat{i}+2 \hat{j}+3 \hat{k}) \mathrm{N}$ acts at a point $\displaystyle (4 \hat{i}+3 \hat{j}-\hat{k}) \mathrm{m}$. Then the magnitude of torque about the point $\displaystyle (\hat{i}+2 \hat{j}+\hat{k}) \mathrm{m}$ will be $\displaystyle \sqrt{x} \mathrm{~N}-\mathrm{m}$. The value of $\displaystyle x$ is \_\_\_\_.
