Newbie at this---Getting to third standard deviation

M

I've been tasked to getting to the third standard deviation. I know
Excel has the STDDEV function, but that only takes you to the first
deviation, right?

Is there a way to use the STDDEV function in Excel to get to the third
deviation?

Any help you have on this would be appreciated.

If you have calculated the standard deviation of a distribution, then three
standard deviations above the mean is just the mean plus 3 times the standard
deviation.
