A cubical cavity of width 0.5 m on a side. The cavity wall is made of Pyrex and the thickness is 3 cm. A block of 1 kg ice at 0 degrees Celsius is contained in the box. The exterior wall temperature of the cube is 20 degrees Celsius. The box is suspended in mid-air of a big room where the air and surrounding temperatures are the same. The convection coefficient in the room is h = 20W/(m^2*K).
