A 'thermocol' ice box is a cheap and efficient method for storing small quantities of cooked food in summer in particular. A cubical box of side 30 cm has a thickness of 5.0 cm. If 4.0 kg of ice is put in the box, estimate the amount of ice remaining after 6 hours. The outside temperature is 45 ° C and coefficient of thermal conductivity of thermocol is 0.01 J s⁻¹ m⁻¹ K⁻¹. [Heat of fusion of water = 335 × 10³ J kg⁻¹]
