Even though you are cutting a strip to replace three 2.5", you can't just multiply the measurement by three because of the seam allowances. If you replace 2 squares, cut a strip 2.5" by 4.5". Because of the complex color layout I would still make the individual blocks rather than trying to cut strips and make a whole row that way. I think you would have real issues in getting everything to line up.
