WAY too many things not said. A lot of people already got to it (castle wall right after moat or land? Moat rectangle, which will make this easy, or circle, which will make it a tad harder but able).

presumably the longest dimension of the boards is 4.5 m, so you can't assume they are 6m wide and just lay them sideways as was mentioned previously. However, you CAN assume (in the absence of any other information) that they are a good 2x2x4.5, which means they will float VERY nicely. Just use a plank as a boat, and drift across...that will work even if the moat is a circle, or the castle walls border right on the edge of the moat.

Lay one plank on top of the other, perpendicular.

That is how you get "a cross".

I have to agree with that.

if its typed out as 'across' 'a cross' is kinda a bad answer

I liked the one about putting the board on the edge, touching both of the nearest shores, than one perpendicular to that, touching the castle. Hard to explain.

If they float then why not just walk across since you can just the remaining half meter?

How can you consider a 2"x2" piece of lumber a plank?
