A concrete slab's thickness can vary greatly depending on the application. Typically, a concrete slab varies between 500mm to thousands of millimeters.
A cubic foot is 12" thick 12" wide and 12" deep. .45 cubic feet per 60# bag of concrete

There are too many variables that are not quantified in the question to answer this. What kind of concrete? (There are different kinds.) Is the concrete reinforced? How is the square of concrete supported? What is the nature of the load and how is it distributed on the slab? We could go on.
(22*6)/2 =66 qubic ft
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.
You will need 17.8 cubic yards of concrete.
That depends on the length and width of your construction.
Base it off : 12" thick a yard of concrete will go 27sqft. 6" thick will go twice as many sqft so 54 sqft. 4" thick will go 3 times as many sqft so 81 sqft 2" thick will go 6 times as many sqft so 162 sqft and at 1" thick it will go 324 sqft. So at 5" thick...1 yard of concrete will go 67.5 sqft

how thick is the paper? example-1mm thick paper (1x2x2x2x2x2x2x2 ect. till youve multiplied 50 times and that equals the thickness in millimeters, all you have to do them is convert the millimeters into miles
27 square feet at 1 f thick
go to any search. and type in concrete calculater
6.94 Cubic Yards
3.6 cubic yards will be enough.
