You have a 85.5-cm-long copper rod with a rectangular cross section of dimensions 5.21 cm by 7.45 cm. You maintain the ends of the rod at 48.7°C and 85.1°C, but otherwise insulate the rod from its environment. Find the heat current through the rod. The thermal conductivity of copper is 385 W/(m·K).
