4.14 cubic metres.Sounds like you are doing a driveway. If it was me I'd buy 5 cu. mtrs. I have always believed it has to be 4 inch [10cm] if cars are to use it.
9' by 18' by 4" thick requires at least two cubic yards.
Rubber cement can dry in 15 minutes if it is not a very thick coat. If it is a thick coat, it will take longer.
one yard of cement will make a 8 x 10 square foot slab at 4 inches thick, that's 80 sq. feet per yard of cement at 4 inches thick.
As a guideline, 4 inches thick, but it would depend on what is going to be sitting on top of it. You may need thicker and/or to reinforce it with rebar.

You will need at least 9.68 cubic yards of cement.
A minimum of 5.93 cubic yards is needed.
0.86 cubic yards is needed.
To determine the number of cement bags needed for 20mm thick plaster, first calculate the total volume of plaster required. For example, if you need to cover 1 square meter, the volume would be 0.02 cubic meters (20mm = 0.02m). Assuming a typical mix ratio of 1:6 (cement to sand), you would need about 0.033 cubic meters of cement, which is approximately one 50 kg bag of cement per 1.5 square meters of plaster at that thickness. Therefore, for 1 square meter, you would need approximately 0.67 bags of cement.
