Monday Madness

on the outside, yes, but not on the inside after you've broken it and laid it flat. and it does look like a spiral shape to me.

had a bit of a think and broke the route into 5 rectangles and added the hypotenuse of all 5 boxes so think the answer is. 1x1 5x5 20x12 5x5 1x1 40.29434 feet.

If you "flatten" the room (kind of like you did the box)… you can do one triangle - two legs and one hypotenuse - and you will get the shortest distance between the two points. You are getting very close to the answer though.

to be honest i can't imagine(picture) how i could flatten the room like you say, or if such a line would then be unbroken when the room was rebuilt so the spider could walk along it to get from point a to b. and my origami skills aren't helping me see it either. so going to have to wait to see if anyone else can get it from all your clues before i have to resort to google to help me.

ok thought if all my rectangles where squares in my route it might be shorter so 1x1 7x7 (never stopped at physical corners but carried it over to wall and ceiling) 12x12 7x7 1x1 and it was. my new answer is 39.5979 not sure this would route would end up at the correct spot tho, my brains stopped working, and think i may have added the lost 8 foot from my rectangle incorrectly to the other 2 boxes.

think i had a brainwave. instead of breaking the route into 5 boxes, i broke it into 2, 16x12 puts her exactly in the middle of side wall 16x12 puts her where she wants to be. and the answer is 40 foot, exactly.

Well done terry1966! That is the correct answer.

Here is how I solve it:

thanks, apple pie is definitely one of my favourites. i really don't know why i made such hard work of getting to the answer, soon as i saw your diagram i remembered i knew that and had seen it before.
