Sand is taken out from its container at the rate of 104 cm/min. By the same pace, the sand is then put in a vertical circular cone with increasing rate of radius 2 cm/min. If when 30 cm' of sand was taken out, the radius of the cone is 6 cm. Find the increasing rate of the height of the sand at that time.
