A closed box is filled with dry ice at temperature of - 78.5°C, while the outside temperature is 21°C. the box is cubical measuring 0.350 m on a side , and the thickness of the walls is 3.0 x10-2 m In one day, 3.0 x10° Joules of heat is conducted through the six walls. Find the thermal conductivity of the material for which the box is made.
