Because Earth's rotation is gradually slowing, the length of each day increases: The day at the end of 1.0 century is 1.0 ms longer than the day at the start of the century. In 72 centuries, what is the total (in hours) of the daily increases in time (that is, the sum of the gain on the first day, the gain on the second day, etc.)?

total=.001ms/day(365days/yr)*72 years*1s/1000ms*1hr/3600s

check that.

Question, wouldn't it be 720 years? Because 10 years = 1 century.

So .001ms/day ( 365days/yr) * 720 years * 1s/1000ms * 1hr/3600s

Actually 100 years is a century
