10 80# bags will fill about 6 cubic feet, so 375 bags should fill 225 cubic feet (30 x 30 x 0.25).ANS 2 -At least in my area, it would be much cheaper ordering this to be delivered by a concrete truck.An 80 lb. bag of concrete is 2/3 of a cubic ft. of concrete. 3 bags is 2 cu. ft. So for 225 cu.ft. youll need 338 bags of concrete.
50lb bags 3.7 60lb bags 3.1 80lb bags 2.3 90lb bags 2.1 These amounts are for using the redi-mix bags.
At 4" thick you will need 1.23 cubic yards.
I use one bag to 1 1/2 bags per hole and fill the rest of the way back with tamped topsoil... whatever came out of the hole.
1.042 CF of concrete per unit

You need 1.16tonne. You need to know the weight of a bag of concrete and then divide 1.16 by that weight and that will give you the answer you need.
10 bags. Each 80 lb bag is 0.6 cubic feet, and your hole is 6 cubic feet.
How many bags of concrete does it take to fill upHey
That would depend on the density of the bags of topsoil.

One pound is 16 ounces, so you can fill 2 8-ounce bags from each pound of mix. With 10 pounds of trail mix, you can fill 20 8-oz bags. Well, 19, since you're probably eating trail mix while you're filling the bags, and you'll have eaten one bag's worth while you worked.
