A Styrofoam cooler has a surface area of 2,700 cm2 and a wall thickness of 3.00 cm. Styrofoam has a thermal conductivity of 0.010 W/m °C. A 2.00 kg block of ice is placed inside the cooler that has a temperature inside of 2°C. When the temperature outside is 30.0°C, the ice lasts for 8.00 hours. If the temperature outside becomes 20.0°C, then how long will the ice last? Ignore the effect of the air inside the cooler.
