an icebox having a wall area of 2m^2 and thickness of 5cm, is constructed of insulating material having a thermal conductivity of 10^-4 cal/scmC degree. The outside temperature is 20 degree celsius and the inside of the box is to be maintained at 5 degree celsius by ice. The melted ice leaves the box at a temperature of 15 degree celsius. If the ice cost 1 cent per kilogram, What will it cost to run the icebox for 1 hour?
