A 1-mm-thick copper plate (k=386 W/mK) is sandwiched between two 7-mm-thick epozy boards (k=0.26 W/mK) that are 15 cm x 20 cm in size. If the thermal contact conductance on both sides of the copper plate is estimated to be 6000 W/mK, determine the error involved in the total thermal resistance of the plate if the thermal contact conductances are ignored.
