<div>I know the requirements are 3 days of life support on the subs. It seems like the math is a little different from difference places I have researched. I have come up with the following. </div>
<div> </div>
<div>*80 cubic feet of O2 per occupant for 72 hours</div>
<div>*23 lbs of sodasorb per occupant for 72 hours</div>
<div> </div>
<div>is this right?</div>
<div> </div>
<div>Thanks,</div>
