Hi, you'd need roughly 2900 bags of 80Lbs. bags. (would actually make 64.4 Yds cubed)
To many!
It's 54, 60lbs bagsand 40.5 80lbs bags.Check http://www.decks.com/calculators/concrete.aspx Answer54in construction a yard of concrete is not in cubic yards. A yard of concrete (in bulk) cost about $75 (Alabama) and is 4 inchs thick. Most Sidewalks, driveways and platforms are only 4 inch thick.So 1 80lbs back covers a little over 1 square foot at 4 inches thick.
go to any search. and type in concrete calculater
If your talking about 4'x4'x4" thick it will take about 12 bags. Most 60# bags will do .45 cubic feet and that slab would be about 5.3 cubic feet wich equals 11.77 bags.. Mike

If memory serves me correctly it takes 3 80lb bags to make a cubic ft so one bag is .3333 cubic ft.
roughly 2900 bags of 80Lbs. bags. (would actually make 64.4 Yds cube better to get trucks and pumper each truck canaries one truck carries about 8-9 Cubic yards

The answer will depend on how large and area you want the topping for. Without that information, no sensible answer is possible.
