About 3 1/2 ". 432 x .375 = 162cf / 27 = 6 cu yards
The easiest way is use Rule 324 (Length in Feet X Width in Feet x Height in Inches) Divided by 324 = Cubic Yards of concrete. Example 4' x 20' x 4"=320 Divided by 324 = 0.9876 Cubic Yards. Or Rule 27 (Length in Feet x Width in Feet x Height in Feet) Divided by 27 = Cubic Yards of Concrete. Example 4' x 20' x 0.33333333'=26.6666664 Divide by 27 = 0.9876 Cubic Yards.
Oops . . . please repost your question and include the depth of the concrete. You have to have all 3 dimensions in order to calculate volume (Cubic Yards of concrete).
You will need 0.56 cubic yards of concrete.
You will need 17.8 cubic yards of concrete.
How thick? Gotta have thickness to calculate cubic yards.
4"x16'x32' = 2.370370... cubic yards
The formula I use is 15 tons = about 12 yards.
Crushed concrete is sold by the ton. One dumptruck will haul between 13 and 15 tons. Your driveway should take around 30 tons if covered 4" thick.
20 times 50 divided by three is 333 1/3
16 ft * 47 ft * 4 inches =16/3 yards * 47/3 yards * 4/36 yards = 9.3 yards approx.

Length in ft x Width in ft. x depth in ft. = Cubic feet, divide by 27 to get yards of concrete needed.

You will have to measure the length and width, in yards, and multiply. You can also measure it out in feet, multiply, and divide by nine. If you're pouring concrete, you need the cubic yards, not the square yards.
Formula: m2 x 1.196 = yards2
