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.
8.25 cubic yards of concrete
1303 Nickels stacked up would be roughly 100 inches. A nickel is 1.95mm thick which is 0.07677165 inches thick.
That would depend on how thick the polythene sheets were.
you would need 37.33 yards of concrete or 38 to be safe

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.

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.
151/9 cubic yards for every 12 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.
About 3 1/2 ". 432 x .375 = 162cf / 27 = 6 cu yards
If you made a sidewalk about 2.5' wide it would be about 13' long.
A pad that is 4 inches think covers 80ish sq ft per yard, so 8 inch would be 40ish sq ft per yard of concrete
four inches minimum. depending on your climate zone, and freeze / thaw. six inches deep would be the preffered. the only need to go deeper would be for large heavy duty trucks, semi trucks....
