Can you figure this brainteaser out.

You could have read the thread, though...

There's a link half way down this thread that explains it.

 

[Kyteland]

I figured it out. It is less than 42.

What ever happened to reading a book for the sake of reading a good book.

Hmmm, I got 40. How did you get 37.6?

 

[RayH]

If the web is large enough, 0.

not sure, I probably did the math wrong, how did you get it?

Since the spider has to follow the walls, you can flatten out the box. The shortest path between two points is always a straight line (in euclidean geometry). There are only 28 distinct ways to flatten out this box, and the shortest one has a length of 40.

Also, it is 30 straight across to the other side and 10 up to the center of the web, which is also 40. I haven't decided if that really matters.

i got 31.6? actually, to be more accurate, the Sqrt(1000).

Isn't it just a triangle w/ the 2 sides that make the right angle being 30' and 10' (10 b/c spider is 1' above ground, and web is 1' below ceiling, thus making it 10' difference)

Then assuming he has a string attached to the web, he can just walk the hypotenuse.

30^2+10^2 = 900+100 = 1000, thus, sqrt(1000).

Draw a picture! Your problems will be solved!

Yeah, thats exactly what I got. I mean, if its a brain teaser, then there is obviously a reason why they chose to use a spider, therefore assume that the spider shoots a string to the web and its a simple application of pythagorean's theorem.

 

[Kyteland]

What is the shortest distance the spider can walk to get to her web?

That means no shooting a web and going across through the air.

 

[Amorphus]

I did this some time ago, also, it was an extra credit problem at one point.

Instead of folding out the box properly, I did this:

I took off the two "ends" of the rectangle. I flattened out the four, and then added another side (making sure to label it properly) on each end. then I added the ends, marking to designate the "tops". then I marked the two locations, and used the pythagorean theorem.

Already thought of that. The spider shoots the string through the air and attaches it to the web, THEN it just walks along the string.
