What is the diagonal measurement of a 4 x 8 foot sheet of plywood?

Reading these answers makes me really concerned for the education in our country. Especially considering the “best answer” is absolutely wrong. A 4x8 sheet from corner to corner is a right triangle. If you are trying to find the hypotenuse aka corner to corner you use the Pythagorean theorem. A2 x B2 = C2 the “2” is squared not sure how to get the little 2 on my phone.

So (48”x48”) + (96”x96”) = C2

2304 + 9216 = C2

11520 = C2

Just have to now find the sq root of 11520. Not going to go into the manual instructions for that but it comes out to 107.33….. or 107 11/32“ roughly.

How anyone can comprehend that you can go corner to corner on a 4x8 (48x96) sheet of plywood and get a lesser number even without understanding the above calculations is beyond me.
