A camber carriers her drinks in an ice chest made of styrofoam. The chest is 40 cm x 45 cm x 70 cm, and the walls and lid are 2.5 cm thick. The contents of the chest are ice, water, cans of soda drinks, and other food, all of which are in thermal equilibrium with the ice water. The temperature just outside the ice chest is 35 degrees Celsius. What is the rate of heat flow through the walls of the box? The thermal conductivity of styrofoam is 0.010 W/ (m*K)
