A thermocol box has a total wall area (including the lid) of $1.0\,\text{m}^2$ and wall thickness of $3\,\text{cm}$. It is filled with ice at $0^\circ\text{C}$. If the average temperature outside the box is $30^\circ\text{C}$ throughout the day, the amount of ice that melts in one day is [Use $K_{\text{thermocol}} = 0.03\,\text{W/mK}$, $L_{\text{fusion (ice)}} = 3.00 \times 10^5\,\text{J/kg}$]
