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.
An 80-pound bag of concrete typically yields about 0.6 cubic feet of mixed concrete. To determine the square footage it can cover, you need to know the thickness of the slab you're pouring. For example, if you're pouring a 4-inch thick slab, an 80-pound bag would cover approximately 12 square feet.
(22*6)/2 =66 qubic ft
You will need 17.8 cubic yards of concrete.
A dime is approximately 1.35 millimeters thick. To convert this measurement to thousandths of an inch, you would multiply by 39.37 (since there are 25.4 millimeters in an inch). Therefore, a dime is about 53.15 thousandths of an inch thick.
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
