Default Need some mathmatical quilting help

I am doing a disappearing 4 patch. I want the final square to be 12 1/2 inches square. What size do the four patches have to be? I am cutting the four patches into 9 squares before I sew them back together.

Here is a picture of the final block I am trying to make. I started with 61/2 inch four patches, but the final block is 1 1/2 inches too small all the way around.

Any help is appreciated
