I need to enter a castle that is surrounded by a 5 meter wide moat filled w/water. I have an aversion for getting wet and only have two 4.5 meter long planks with no rope, nails, etc. How do I get across?

i really do not know the answer but i think the pythagorean theorem stuff about that moat is pretty possible.

lets say that the castle is square and the moat is a square around that.
Draw a diagram of that.
Now look at a corner.
Draw some lines that divide a corner of the moat into a small square that is 5 m by 5 m.
The diagonal of that small square is 7.07 meters (Pythagorean theorem). Your board is too short to put diagonally.
Put one board diagonally across the bottom corner of the moat. Put the other board with one end resting on the first and the other end on the castle corner.

Doesn't this castle have a draw bridge?
