Give me right solution with clear calculations 

4-86 The walls of a furnace are made of 35-cm-thick e (k = 1.1 W/m-°C and a = 5.9 × 10-7 m²/s). Initially, the furnace and the surrounding air are in thermal equilibrium at 20°C. The furnace is then fired, and the inner surfaces of the furnace are subjected to hot gases at 1000°C with a very large heat transfer coefficient. Determine how long it will take for the temperature of the outer surface of the furnace walls to rise to 20.1°C. Answer: 114 min %3D
