5. A silver ingot (25 mm x 40 mm x 150 mm) with a surface temperature of 40°C is cooling in air at 20°C. If the ingot is sitting on an insulating surface that completely stops heat flow through one of the 40 mm x 150 mm faces and the heat transfer coefficient between the ingot and the air is 18 W/m²K, find the rate at which the ingot is cooling. Assume the temperature within the ingot is uniform.
