A ice box of styrofoam (thermal conductivity = `0.01` J `ms^(-1)K^(-1)`) is used to keep liquid cool. It has a total wall area, including lid, of `10.8 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^(@)C`, the rate of flow of heat into the box is (in `J//s)`
