Puzzlers #5. Card Stack

It is impossible in reality, but assuming that one could tear a playing card in two, put the halves together and tear again (getting 4), put them together again and tear (getting 8), put then together and tear and so on 52 times.

Do you think that the pile would be more or less than 10 miles high?

Concepts involved:

  • thickness, exponential.
