Thread: am I smarter than a 5th grader (nooooooo!!!!!!)

I agree with the paper test sheet. You'll probably have to tape several pieces together. I would also make it slightly oversized (like an inch or so) and trim it down to square. Just MHO.

Pythagorean theorem. I knew there was a name for that formula!

I think if Mr. Pythagoras had been a quilter, there would be a better way to figure this out.

I always make them slightly larger since it is easier to trim than to add. I thought that is was 1.5 that you multiplied but maybe that is for setting triangles. If you don't use it, you lose your math skills. Those 5th graders were much smarter than any 5th grader I ever met.

I'm puzzled you know the diagonal length.
usually I know the length of the sides then can work from there size of block and how many. You can try different sizes of block which will generate different number of blocks.
far easier than playing with Pythagarus

A squared + B squared = C squared. C is the measurement from corner to corner. In this case C=38. Since we're dealing with a square, A = B.
Therefore, 2 * (A * A) = (38 * 38). or 2*(A*A) = 1444. If you divide 1444 by 2, you'll get the value for A*A.
A * A = 722. Now use the square root function on your calculator to get 26.87.

I would round up to 28 or 29 to allow for seam allowances and the fudge factor. As someone else said it's easier to trim fabric than add to it once it's cut.

I am just "pyth-ed".
