call a concrete company and ask how much concrete will I need to pour a slab 12' X 12' X 6". they will tell you how much and a price.
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
2.2 Yards
Depends on how thick the concrete pad is. At 4 inches thick and allowing for a little waste and imprecise measurements, about 350 square feet. You can check out more options with the concrete calculator below.
A cubic foot is 12" thick 12" wide and 12" deep. .45 cubic feet per 60# bag of concrete
The question does not provide units of measure which are important in answering the question. However, it is likely that the slab is 1400 square feet and that the slab thickness is 3 inches. A cubic yard of concrete is 3 ft by 3 ft by 3 ft, or 27 cubic feet. To solve the problem, you convert the slab size into cubic feet by multiplying the length in feet by the width in feet (to get 1400 square feet) by the thickness of the slab in inches divided by 12 inches per foot or 1400 * 3 / 12 = 350 cubic feet. To convert to cubic yards, divide the 350 cubic feet by 27 cubic ft/cubic yard to get 12.96 cubic yards. So, order 13 yards of concrete.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
How many square yards in a 20x18 feet 3 inches thick
39.1116 cubic yards
It depends on what "5 thick" is: 5 inches thick, 5 feet thick, 5 yards thick, 5 miles thick etc.
I think you mean 6 inches thick, not 6 feet thick. You would need 200 cubic feet, or 7.4 cubic yards.
one (1) cubic yard of concrete four inches thick will cover 80 sq. feet. 85 yards x 81 = 6885 sq. feet.
22.2222 cubic yards (the 2s keep on going).
151/9 cubic yards for every 12 inches thick
One cubic yard covers 81 square feet 4 inches thick.
Apples and oranges. Without knowing how thick the 450 sq. ft. area is or how thick you want it to be you can't convert to cubic yards. A cubic yard has 27 cubic feet. One square foot 3 inches thick would be 1/4 cubic feet. 4 sq. ft. 3 inches thick would be 1 cubic foot. 450 sq. ft. 3 inches thick is 112 1/2 cubic feet or just a bit over 4 cubic yards. 450 sq. ft. 4 inches thick is 150 cubic feet or 5 1/2 cubic yards.
11 yards, 10 feet, and 7 inches. 9 inches + 10 inches is 19 inches. 2 feet + 7 feet is 9 feet. 6 yards + 5 yards is 11 yards. One foot is 12 inches, so we can turn 19 inches into 1 foot and 7 inches, so we have 10 feet and 7 inches instead of 9 feet and 19 inches.
7 yards, 11 feet, 15 inches or 11 yards, 3 inches
