A closed box is filled with dry ice at a temperature of -93.7 ^{o}C, while the outside temperature is 21.5 ^{o}C. The box is cubical, measuring 0.348 m on a side, and the thickness of the walls is 4.20 × 10^{-2} m. In one day, 3.33 × 10^{6} J of heat is conducted through the six walls. Find the thermal conductivity of the material from which the box is made.
