Answer: 23 1/24 CM.
-- I hope you stay safe and extra healthy. Don't let those annoying hands of yours touch your germ-free face! Make sure to wash your hands extra this time and use a lot of PURELL, just, don't dry your hands out, so, make sure you have enough hand lotion. Hope this helped! (Also, masks are great! Don't use gloves because you put germs on the gloves, then, when you take them off, you touch the germs that were on your gloves.)
