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.
To calculate the volume of concrete needed, first convert all measurements to feet. The sidewalk is 3 feet wide (36 inches), 0.33 feet thick (4 inches), and 60 feet long. The volume in cubic feet is calculated as: 3 ft (width) x 0.33 ft (thickness) x 60 ft (length) = 59.4 cubic feet. To convert cubic feet to cubic yards, divide by 27; thus, you need approximately 2.2 cubic yards of concrete.
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
To calculate the volume of a concrete slab that is 40 feet long, 60 feet wide, and 6 inches thick, first convert the thickness to feet (6 inches = 0.5 feet). The volume in cubic feet is 40 x 60 x 0.5 = 1,200 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard). Thus, 1,200 cubic feet is approximately 44.44 cubic 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.
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.
There are 9 square yards in a cubic yard at a thickness of 3 inches. This is because there are 9 square feet in a square yard and 36 cubic feet in a cubic yard, so the area is 9 square yards if the thickness is 3 inches.
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.
You will need about 3.7 cubic yards (around 4.75 tons) of gravel.
