It all depends on the type and sizes of the steel used. It also depends on the load that the concrete has to take at certain points. 7865kg is the weight of a cubic meter of steel. Typical examples; A pile cap could contain 400kg/m3 A heavy duty industrial slab or structure could contain 200kg-400kg/m3 A footpath could contain 40kg/m3 (all depends on the design, but numbers above should give you a rough answer)
For a 1000 sqft slab with a thickness of 4 inches, you would need approximately 33 cubic meters of concrete. This calculation is based on the assumption that 1 cubic yard of concrete covers 81 square feet at 4 inches thick.
If you know the dimensions of the slab, assuming that the slab is solid and in the shape of a rectangle, box, or square, you can calculate the volume with the formula: LxWxH which is length times width times height. This will give you the volume of the slab in cubic units (meters, feet, inches, whatever). Depending on the type of steel, you will have a different density ratio which can be used to calculate the weight of the slab. The density of low grade steel is something on the order of: 7850 kg/m3 so you would multiply your volume by the density ratio to get kilograms. If you know the weight of the slab and the type of steel, you can calculate the volume by dividing the weight by the density ratio. I hope this helps, perhaps you could provide more details on the type of steel and the exact property of the slab that you need (volume, weight, density.

Concrete has a density of about 2,3 tonnes per cubic meter (varying slightly with the type and amount of ballast). 2400 kg/m3 may change depending on the mix design. You can also get lightweight concrete at 1750 kg/m3. k.k
