TOTAL QUANTITY OF PLASTERING=3.05*3.05*.01=.093 cu.m
by thumb rule
.75 cu.m of plastering requires =350kg of cement
1750 kg of sand for
the ratio of 1:5 (the weights are calculated with specific
gravities) from this


add 30% extra for wastage and uneveness=.121 cu.m
so for .121 cu.m of plaster requires = 56.5 kg of cement
282.5 kg of sand

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
