8.25 cubic yards of concrete
387 cubic feet. This is because 43x18x0.5 (as six inches is 1/2 of a foot) =387.
Multiply length times width. IF your driveway was 1 foot thick that would be the number of cubic feet of concrete. HOWEVER- it is only 4 inches thick. That is .33 ft (one third of a foot). So take your answer you got from multiplying LxW, and divide by 3. That will be the number of cubic feet of the driveway's volume.
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.
According to the U.S. Treasury a dollar bill is .0043 inches thick. Therefore, a stack of 1,000 one dollar bills would be: 4.3 inches thick.
1303 Nickels stacked up would be roughly 100 inches. A nickel is 1.95mm thick which is 0.07677165 inches thick.
1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
Depends on how thick it is. At 4 inches thick, you would nee about 5.5 cubic yards adjusting for safety. At 6 inches, you'd need about 8 cubic yards. You can play with different thicknesses with the linked concrete pad calculator.
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.
(10x16)/3 =53.3 cu ft 53.3/27=2 cu yards
30.81 cubic yards
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
That depends on how DEEP you want the concrete !
151/9 cubic yards for every 12 inches thick
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.
If you made a sidewalk about 2.5' wide it would be about 13' long.
I would guess about 70-80 bales
about 17 yards of concrete (it's sold by the cubic yard)
