Approximately how long should it take 8.78 kg of ice at 0oC to melt when it is placed in a carefully sealed Styrofoam icebox of dimensions 27.2 cm x 35.7 cm x 51.2 cm whose walls are 1.20 cm thick? Assume that the conductivity of Styrofoam is double that of air and that the outside temperature is 30.9oC.(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to start with the equation:

delta Q/ delta t = kA* [(T1-T2)/l]

But I have a volume, and I guess I didn't know if V could replace A, but it doesn't seem like it should. Then even if it could, I would have calculated a J/s. And also, do i need to incorporate a phase change in this problem? Any help would be appreciated.
