A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.

How do you estimate long it would take to construct a cubic meter by placing one centimetre cube at a time show all calculations?
You can get an estimate by placing a call or going into the repair shop or auto body shop and requesting a rough estimate on the cost it would take to repair your car
C 11 specification
There is no constant value for the ratio of the rebars and concrete volume. The rebars depends on the structural designer's safety factor and the factors affecting the framing like wind, earthquake and soil.
Middle strip
The unit weight of 16 mm reinforcement is 1.58 kg/m
350x450mm with 12-16mm rebars on 5m span
Waist slab is used in case of stairs. The rebars are bent at some angles on which steps are built.
The unit weight of rebars is typically around 7.85 kg/m³. In a reinforced concrete mix with a compressive strength of 60 MPa, the amount of reinforcement steel used is usually between 1-2% of the total volume of concrete. Therefore, the weight of rebars per cubic meter of reinforced concrete at 60 MPa would be approximately 78.5 kg/m³ to 157 kg/m³.
That would depend on the height of the wall...
