OK here we go...
my house is 28x68 the "attic" space has about 12 inches of room in it.
Lowes and Home depot sell the exact same product for blow in insulation it is 13"x15"x25" in size contains approx 40sqft of insulation I am guessing that is at a 2" height level for the 40 sqft. I have about 1-2inches in the "attic" now how many bags of this stuff do I need to buy to fill the attic?
BTW I am HORRIBLE at this kind of math so that is why it is posted here

The level for cellulose as an R-19 is 40 ft2 @ 6" thickness. That extra volume comes from the product being 'air fluffed' as it's sprayed.
With that, your house will require approx. 1900 ft2 ÷ 40 ft2 per bag = 48 bags.
Now the tough part is being able to spray it in the attic itself.
