How many kg of steel is required in 1m3 of concrete?

Minimum quantity of steel required for 1m3 concrete slab is 1%, now 1% of 1m3 = 0.01 m3, and we know that 1m3 steel weight is 7850 Kg, so weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so minimum quantity of steel required for 1m3 concrete slab is 78.50 Kg.
