Oh boy I'm showing my lack of math skills.
I'm having problems trying to nail down a quantity to nail down a price for blown in cellulose.

2X6 walls 2 ft on center 8 foot high.

If I'm figuring this correctly one cavity should be about 7.68 cubic feet?

From what I've read a dense pack target is 3.5 lbs per cubic feet?

So for one cavity it would take 26.88 lbs?

One net weight 18.10 lb bag is $5.99 and this isn't enough for one cavity?

Am I correct on this? I guess it seems like a lot but it is 2' on center.
