I am undexterous and the wrapped ones last seemingly forever whereas a cut cheese block doesn't seem to (although I've never gotten a block of American).
Admittedly the slices probably tend towards being thicker when you do it yourself lol
I think if you get one of those wire cheese slicers you can measure it. But yes the freshness and convenience might be out the window if you aren't diligent about wrapping it back up.
On the other hand, think of all the things you can do with a block of american cheese
