Answer:

31536000

Explanation:

So there are 60 seconds in a minute, and 60 minutes in an hour so we do:

60x60=3600

That is how many seconds are in an hour. We know that there are 24 hours in a day so we do:

3600x24=86400

That is how many seconds in a day. We know that there are 365 days in a year so we do:

86400x365=31536000

There are 31536000 seconds in a year
