**EXTRA CREDIT. drie boow Q.7 A loaf of bread at 120°C is cooling in air at 20°C. The dimension of the loaf is 10cm by 12cm by 20cm. h = 10W/m²K, &=0.76, K=0.121 Find the heat loss from the bread. Hint: Conduction from the loaf to cooling rack is negligible due to the small area involved. First, find the total area (area of all sides) Heat loss is therefore a combination of convection and radiation. 2 pts.
