6 feet 8 inches = 6*12 + 8 = 72+8 = 80 inches.


5 feet 10 inches = 5*12 + 10 = 60+10 = 70 inches.


The difference is  80-70 = 10 inches.


Divide 10 inches by 3 inches  10%2F3 = 3 1%2F3 inches.

5'10" is 70", 6'8" is 80". Subtract 70 from 80, divide the result by the standard deviation, and round UP.
