An ice box made of styrofoam (thermal conductivity `=0.01" Jm"^(-1)s^(-1)K^(-1)`) is used to keep liquids cool. It has a total wall area including lid of `0.8" m"^(2)` and wall thickness of 2.0 cm. A bottle of water is placed in the box and filled with ice. If the outside temperature is `30^(0)C` the rate of flow of heat into the box is : (in `J-s^(-1)`)
