A brick of 203 ×102 ×57 mm in dimension is being burned in a kiln to 1100°C, and then allowed to cool in a room with ambient air temperature of 30°C and convection heat transfer coefficient of 5W/m2K. If the brick has properties of rho = 1920kg/m3,cp= 790J/kgK, and k = 0.90W/mK, determine the time required to cool the brick to a temperature difference of 5°C from the ambient air temperature
