The answer will depend on what information is available. Ideally, you know the length, breadth and height (in the same units of measurement) and simply multiply the three together.
I'll make the assumption that 150 is meant to be metres. 150x6 is 900, x 2.5 is 2250
4.074 cubic yards for every foot the slab is thick.

You cannot. In general there is no relationship between the area of a slab and its thickness.
You need to specify the slab's width and the length as well.

Concrete is sold in cubic (volume) measurements not square (area) measurements.
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet

to answer your question, one must know the thickness of the slab? then only the weight can be calculated
Slab area multiply 1.4 times.
That's going to depend on the shape of the cubic meter, because the drying happens where the concrete is in contact with the air. A slab will dry faster than a cube or a pier.
For a standard 4-inch thick slab, this area needs at least 3.95 cubic yards.

In order to estimate rcc roof slab you must measure the roof and calculate its area. Then you must contact a professional to see how much slab will be needed.
A cubic metre (or 'stere' as it is correctly known ) is 35.1 cubic feet. -In wet asphalt concrete that weighs about 5,250 pounds - just over 2 and a half tons !
