1 ft = 30.48cm 1 ft^3 = (30.48)^3 = 28,316.85 cm^3 or cc Steel's (Iron) Specific gravity / RD is 7.8 ~ 7.8 g/ cm^3 or cc therefore, 28316.85cc = 1 cubic ft/ 1 ft^3 = 7.8g*28316.85 = 220,871.43gms or 220.871 kg
About 0.42 ounces. Specific gravity (compared to water) about 0.73
On Average it's 450 Pounds
