I am having difficulty with a program in my CS class right now and I am wondering if you guys could help.

Basically, I need to find the length/width (should be equal) of the 4 corners(I'll call this variable 'x') of a piece of cardboard, to cut them out to fold the sides up into a tray (hopefully you guys can understand that description :/). The user inputs the total length of both sides of the box, and I need to figure out how to calculate the smallest possible length that x could be.

I have currently figured out how to find x if length and width are different sizes, but when they are equal I cannot figure out how to find it.

Ex. of how to find when they are different sizes:

If L > W

D= L-W

Df= D**.5

And I believe that's all I need to do (sorry I dont have the code w/ me and I wasn't at school today so it's not really fresh in my head).

Do you guys have any idea how I can figure it out when the sides are equal? I'm sorry that my description was awful, just ask if you need me to clarify something.

Your example probably doesn't handle the case L<W, though that's a simple fix.

I don't think I know what a tray is. If you hand me a 6-inch square of cardboard and a pair of scissors, I would cut out a 1-inch by 1-inch square at each of the 4 corners. Then I fold up all 4 sides and voila, a tray. But obviously that's not consistent with the rest of the problem since my choice of 1 inch at the corners could be replaced by 1/2 inch or 1 millimeter or 1 micron, etc.


Yea, it covers L <W, I just wanted to show how I got my answer. When L and W are equal that doesn't work though, as there is no difference :/
