How much insultaion do I need?

We need to insulate a crawl space and I need to know how much insulation I need. I called the hardware store to price the insulation which is R 19 and covers 49 Sq ft. The guy said I needed 11 bags so to check this I went to the online calculator and it said I only needed 1 bag so maybe I am useing the calculator incorrectly. I need enough to cover a 22 Ft Length by 24 Ft width. Can someone help me find out how much I need.

Thanks Sherry

Your square footage is 22ft x 24ft = 528sq.ft. If each bag has about 50sq.ft. and considering a little waste, 11 bags is a good estimate.

49sq.ft. is an area 7ft. x 7 ft.
