A closed box is filled with dry ice at a temperature of -77.6 °C, while the outside temperature is 21.8 ° C. The box is cubical, measuring 0.33 m on aside, and the thickness of the walls is 0.072 m. In 1 hour 620,000 J of heat is conducted through the six walls. Find the thermal conductivity of the material of the box. k = J/(s*g*° C) %3D
