How do you calculate beam load?

How to Calculate Load on Beam

300 mm x 600 mm excluding slab.
Volume of Concrete = 0.30 x 0.60 x 1 =0.18 m³
Weight of Concrete = 0.18 x 2400 = 432 kg.
Weight of Steel (2%) in Concrete = 0.18 x 2% x 7850 = 28.26 kg.
Total Weight of Column = 432 + 28.26 = 460.26 kg/m = 4.51 KN/m.
