10feet = 10/3.28=3.048m
volume = 3.048x3.048x.01=.093 cubic meter
for dry material factor is 1.2
so quantity of dry material=0.093x1.2= 0.11cum
now the ratio is (1:5)
so cement=0.11/6 =0.018cum=0.64(.018x28.8bags)
=0.518bags=25.92kg
sand=0.018x5=0.09cum=3.17cuft

As we know that steel is a tension member but why we are using STRUCTURE STEEL as a COLUMN (Without concrete) where column is a compression member and compression strength of steel is very low
