A 56 kW electric furnace measures 1.2m x 1.3m x 0.7m. When the temperature inside the furnace is 1613 ºC, a block of aluminum with a mass of 283 kg and a temperature of 18 ºC is placed inside. Assuming the heat loss from the furnace walls is 529 W/m, how long (in min) will it take to heat the block to the furnace temperature? (Specific heat of aluminum is 0.90 kJ/kg. K)
