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.
U need 1.63 80lb bags per square ft so 131bags to do 8ft by 8ft
Hi, you'd need roughly 2900 bags of 80Lbs. bags. (would actually make 64.4 Yds cubed)
You will need 17.8 cubic yards of concrete.

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.

Figure about 1/2 cubic foot per 60 lb bag. The basic formula is to use equal amounts of cement, sand, and gravel. There are 27 cubic yards per cubic foot. It depends upon how thick you are planning to pour the concrete. For one foot thick, you would need 9 cubic feet of concrete. For 6" thick, you would need 4 1/2 cubic feet. I'll give you the answers for 1 ft thick and for 6" thick. For 1 foot thick, you need 9 cubic feet at 1/2 cubic foot per 60 lb bag equals 18-60 lb bags. That's six 60 lb bags of concrete, plus six 60 lb bags of sand, plus 360 lbs of gravel. For 6 inches thick, divide each of these by 2 to give 3-60 lb bags of concrete, 3-60 lb bags of sand, plus 180 lbs of gravel.

To make one yard of concrete from 80# bags you will need about 40-45 bags. Each bag is about .67 or 2/3 cubic foot. you will need 27 cubic feet to make 1 cubic yard. Cheaper to have a redimix truck deliver, and a lot less work.
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
10 yards
Depends on how thick the slab is, but 4" thick (.33 or 1/3 of a foot thick) would be typical. So multiply 10 x 10 = 100 square feet of area times .33(thickness in feet) equals 33 cubic feet. A 90 lb. bag contains about .66(two thirds) of a cubic foot of concrete, so you would need about 1 1/2 bags per cubic foot or 50 bags for 10'x10'x4"
At 4" thick you will need 1.23 cubic yards.
