Model H is 580*280*12*14. How much is the theoretical weight of the steel?It's better to list the complete formula, thank you!
Quality = volume * density, the density of steel, 7.85g/cm3,0.785 is a fast algorithm, the essence should be: unit weight =144.64cm2*100cm*7.85g/cm3=113542.4g=113.54kg. 0.785=100*7.85/1000.
Sectional area=（H＋2T =（TW）2bt 580×2×14）＋2×280×12×14 = 144.64cm2
