The bottom face of a horizontal slab of thickness 6mm is maintained

The bottom face of a horizontal slab of thickness 6mm is maintained at 300C. The top face is exposed to a flowing gas at 30C. The thermal conductivity of the slab is 1.5 W/m-K and the convective heat transfer coefficient is 30 W/m-K. At steady state, the temperature (in C) of the top face is
