Just completed my 30x30x10 shop, need to add a apron in from of the door. I went online at Lowe's and talked to one of their chat people. I ask about how many of 80 pound bags would I need to do a 4" thick, 10' long and 30" wide took him about 10 minutes to get back..He said I would need 167 80# bags. I was thinking 20 at the most I told him..he said be best to get 175 bags and return what I don't use...heh

thanks, I guess tar paper is okay to use as a in between of the shop slab and new apron. I tried fill dirt but I don't think it would hold up well over time. I hope 30" is wide enough so my mowers won't drag going in

Your math is off- think about the size of an 80# bag. It's about 2sf at about 4-6" thick. Your pour is 300sf so about 150 bags would do.

Another way to figure (and the normal way to Calc concrete) is by the yard. 30x10x.33 is about 3 3/4 yards.

You need volume, so 10'x2.5'x.33333' (10' long x 30" wide x 4" deep). I come up with 8.333333 cubic feet. 80# bag yields approx .6 cubic feet. You would need 13.88888 bags, round up to at least 14 bags.

Frost got under my apron (24" wide 4" deep) across the front of my shop and under the floor of the shop and raised up an inch and jammed my door so I could not open it. I would consider putting an edge deeper (if your shop floor does not already have deeper edge) to block frost (18" would work in my case).

It does not take much area that is deeper than 4" to require more bags. Either have extra quickcrete or gravel on hand to help fill if needed.

Um...I think your math is a bit off by a factor of 10x.
