Carpet Cutting Puzzle
Time for another puzzle. I found this one at a puzzle site in the Netherlands. Despite having a Dutch web address, the site appears to be entirely in English.
Anyway, here's the puzzle: I have a room that's 9 metres by 12 metres, and I'm going to have an 8 metre by one metre aquarium right in the middle of it (lengthways). Quickly noticing that the area of open floor will be exactly 100 metres (9x12-8), I buy a 10 metre by 10 metre carpet that was going cheap on eBay. But how to cut it to fit the shape? I don't want to cut the carpet more than necessary. What's the smallest number of pieces I must cut the 10x10 metre carpet into, to make it fit the 12x9 space, with the 8x1 hole in the middle? Hint: It's less than four. I've attached the picture of the situation take from the above web site. Answers in Spoiler:
if possible, please.
I hope this non-verbal, non-numerical, non-logic puzzle will make a nice change. Last edited by pdurrant; 08-07-2010 at 03:11 PM. Reason: Removed unhelpful transparency from the picture. Added upper limit to number of pieces. |

Thanks G. I've been a lurker for some time and decided to add my input to the wonderful puzzles that pdurrant has been providing.
Thanks pdurrant for providing me a use for my brain power besides reading all the time and watching movies. Lol. Keep up the good work. Was trying to get fewer cuts and I still can't figure it out. |

I must say, there are much more ways to cut a carpet to 4 pieces than I suspected!
