how many seconds are in 3 years?

Do any of those years include a leap year?

That would add another day to the count.

The formula would normally be:

60sec x 60 minutes x 24 hrs x 365 days x 3 yrs = 94608000 seconds (roughly)

(remember that actually each year is about 365 1/4th days in lenghth. So, if none of the years had a leap year, change the above formula to be

365 1/4th, or 365.25 days. This will add another 64,800 seconds for three years of 365.25 day years

60*60*24*365*3 = 94608000 (if you want to be exact, a day has 86387 seconds, meaning the answer would be 94593765 seconds)

3 years = 94 670 777.9 seconds

calculator

60 seconds in a minute, 60 minutes in an hour, 24 hours in a day and 365 days in a year on average unless you're factoring in leap year, so all you have to do is the multiplication and you should have your answer. Unfortunately my calculators not handy and I'm rusty without it.
