Bear bag size

[lkaluzi]

What size bear bag do I need to hold 4-5 days of food (assuming the standard 2 pounds per day)? I was thinking about getting a dry bag but I don't know how many liters would work.
Thanks

I carry a 20L Sea-to-Summit Ultra-Sil dry sack. Plenty big enough. Suspend it with 2mm cord....... paracord is overkill.

Cheers!
