How many seconds are there in one century? Use "E" for scientific notation

The answer is 3.154e+9

If you follow the formula below you will arrive at about the same answer depending on the decimal places you want to include:

(100 years/1 century) x (365 days/1 year) x (24 hours/1 day) x (60 minutes/1 hour) x (60 seconds/1 minute)

Through the process of cancellation, you will eventually arrive at the number of seconds there are in a century because those will be the only units left in the formula.
