A loop ABCDEFA of straight edges has six corner points $\displaystyle \mathrm{A}(0,0,0), \mathrm{B}(5,0,0), \mathrm{C}(5,5,0)$, D($\displaystyle 0$, $\displaystyle 5$, $\displaystyle 0$), E($\displaystyle 0$, $\displaystyle 5$, $\displaystyle 5$) and F($\displaystyle 0$, $\displaystyle 0$, $\displaystyle 5$). The magnetic field in this region is $\displaystyle \overrightarrow{\mathrm{B}}=(3 \hat{i}+4 \hat{k}) \mathrm{T}$. The quantity of flux through the loop ABCDEFA (in Wb) is \_\_\_\_.
