1. The problem statement, all variables and given/known data 2. Relevant equations Q = kAΔT/L 3. The attempt at a solution so I need to find the volume of the cooler, and then the volume is the volume is ice in it? then I need to find the surface area of 1 side of the cooler, than multiply it by 6. then plugging in the total area in Q = kAΔT/L is this a good approach to the problem?
