I-beam — 60.24 kg per metre, 76.7 cm² cross-sectional area. IS 808 Table 5 - Column / Heavy Beams.
Column / Heavy Beams (SC, HB). Reproduced as printed in IS 808 Table 5 - Column / Heavy Beams.
As printed in IS 808 Table 5 - Column / Heavy Beams. 200 mm deep, 200 mm wide. Units are shown on every row, because the two standards on this site use different ones for the radius of gyration.

Total weight is the mass per metre multiplied by the length and the number of pieces. Ten pieces of SC 200 at six metres each is 60.24 × 6 × 10 = 3,614 kg. There is nothing else to it — the standard publishes the mass, so no one needs to compute it from the area.
You can check that mass against the area on this page: 76.7 cm² of steel at 7 850 kg/m³ is 60.21 kg/m. Every row in this dataset was checked that way, which is how the contradictions flagged on some of these pages were found.

IS 808 : 2021 gives SC 200 a mass of 60.24 kg per metre. Its printed cross-sectional area of 76.7 cm² agrees: 76.7 cm² of steel at 7 850 kg/m³ works out at 60.21 kg per metre.
361.44 kg. Mass per metre times length: 60.24 × 6. Ten such pieces come to 3614 kg.
It is the same section under the name IS 808 : 2021 gives it — the 2021 revision of IS 808 dropped the "IS" prefix, so a drawing saying ISSC 200 means this section. Check the edition before assuming the figures match, though: this page publishes the current tables, and a great many tables in circulation were copied from the 1989 edition.
200 mm deep and 200 mm wide, with a 9 mm web and 15 mm flanges.

What is ours. The selection and arrangement of these tables, the checks run against them, and the findings those checks produced — which rows disagree with themselves, which figures were superseded by amendment, and which could not be read — are QuickBOQ’s work, and so is this wording. Quote the numbers freely; they belong to everyone. Copying the compilation and the commentary is a different thing, and we would rather you linked to it.
