An ice cube is melting in a glass of water. The rate at which it melts is proportional to its surface areas. Initially, the ice cube has a volume of 11 cm^3, and also initally, the instantaneous rate at which the length of the cube is decreasing is 0.15 cm/min. Derive an expresion for the mass balance describing this process. Assume that the ice stays in cube shape at all times. Choose the ice cube as the system.
