A brick of 203 × 102 × 57 mm in dimension is being burned in a kiln to 1600°C, and then allowed to cool in a room with ambient air temperature of 30° C and convection heat transfer coefficient of 5 W/m^2·K. The brick has properties of rho = 1920 kg/m^3, cp = 790 J/kg·K, and k = 0.90 W/m·K.
Determine the time required to cool the brick to a temperature difference of 5°C from the ambient air temperature.
