How many days equal 400 hours working 8 hours 5 days a week?

Oh, dude, let me break it down for you. So, if you work 8 hours a day for 5 days a week, that's 40 hours a week. To get to 400 hours, you'd just divide 400 by 40, which equals 10 weeks. So, 10 weeks of working 8 hours a day, 5 days a week equals 400 hours. Easy peasy!
