Thisquestion needs clarifying. The question should be 'how much does a CUBIC metre of concrete weigh'. A square metre of concrete would have to have a thickness to make volume.
130 cubic meters for each meter the 130-square-meter slab is thick.
In an average 5.39m2 per Cubic meter of concrete
it is .4 square meter

It depends on the size of the concrete blocks
How much steel required in one cubic meter concrete = 100kg or 0.1ton
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.
2.83 CM of Concrete
No. A cubic metre is a volume measurement, what you can fit in a box, 1x1x1 metres in dimension. A square metre is an area measurement corresponding to 1x1 metre.
1 (square meter) = 10.763 square feet.
One square meter = ~1.2 square yards.
