A concrete slab's thickness can vary greatly depending on the application. Typically, a concrete slab varies between 500mm to thousands of millimeters.
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.
4 To 6 inches
Floating slab is a type of mat foundation. It consists of a hollow mat formed by a grid of thick reinforced concrete walls between two thick reinforced concrete slabs. The weight of the soil excavated from the ground is equal to the weight of the entire building, so that pressure on the soil is unchanged from the original condition, making the building float on the soil
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
Your question is missing a verb. Do you want it's weight? It's cost? Something else?
For a 4-inch thick slab you will need at least 1.2 cubic yards.

You will need at least 14 cubic yards.
A 6-inch concrete slab can typically support around 150 pounds per square foot.

4.074 cubic yards for every foot the slab is thick.
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
