Did you know that chemical engineers are developing hydrogen fuel cells to supply heat and power?

**NOTE: The May question is now closed, but you can answer the current question here. **

A mathematician states that if one folds a piece of paper in half, and folds it in half again and continues to do this 43 times, the height of the stack of folded paper will be greater than the distance between the earth and the moon. Can you prove it by simple calculation?

- This a theoretical question, it would be impossible to physically fold a piece of paper in half and in half again, and so on until you 43 times.
- The distance between the earth and the moon is 385 000 km and the thickness of paper is 0.006cm.)

Number of folds | 1 | 2 | 3 | 4 | 5 | ... | ... | 42 | 43 |

Number of pieces of paper | 2 |
