An ice skating rink decides it will save energy by insulating the ink each night when not in use. The ice temperature is 265K and the air temperature is 290K. The rink is rectangular with measurements of 20.0m by 100.0m. The insulation consists of cork-board panels that are 1.0m X 2.0m X 0.020. The rink bought a total of 3000 panels. They can lay the panels onto the ice in a variety of ways. For example, they can place a three-panel layer uniformly over the ice, or they can provide half the ice with a four-panel layer and the other half with a two-panel layer. Of these two configurations, which would you recommend? Justify your answer with a calculation.
