In a cement factory, a machine takes one kilogram of cement. It then divides this into rectangles each weighing 10 g. These rectangles are then stamped into disks of cement each weighing 6 g with the remaining cement discarded. These cement disks are next packed into bags of 4 which are sealed and finally packed into boxes, each containing 6 bags ready for dispatch to the shops. What percentage weight of cement out of the original kilogram will be contained in COMPLETELY FILLED boxes (i.e. those containing a full 6 bags)?
