A $0\mathrm{.}6-$m$-$diameter, $1\mathrm{.}9-$m$-$long cylindrical tank containing liquefied natural gas $($LNG$)$ at $-168$C is placed at the center of a $1\mathrm{.}9-$m$-$long, $1\mathrm{.}4-$m $1\mathrm{.}4-$m square solid bar made of an insulating material with k $=0\mathrm{.}0002$ W$/$m$$K$.$ The outer surface temperature of the bar is $12$C$.$ The shape factor for the configuration is given to be:

The steady rate of heat transfer to the tank is $0\mathrm{.}4651$ W$.$ Determine the LNG temperature after one month. Take the density and the specific heat of LNG to be $425$ kg$/$m$3$ and $3\mathrm{.}475$ kJ$/$kg$$C$,$ respectively. $($Include a minus sign if necessary.$)$

$$

The temperature is $$C$.$
