Sam keeps marbles in a box everyday in such a way that the number of marbles in the box doubles with each passing day. For e.g., he puts in 1 marble on the first day, 2 on the second day, 4 on the third day and so on. The box gets full on the 18th day. On which day was the box half full?
That was too easy. Better question, how big was the box?
