square hollow section — 23.01 kg per metre, 29.31 cm² cross-sectional area. IS 4923:2017 (Amd. 2) Table 1 - Square Hollow Sections.
Square Hollow Sections. Reproduced as printed in IS 4923:2017 (Amd. 2) Table 1 - Square Hollow Sections.
As printed in IS 4923:2017 (Amd. 2) Table 1 - Square Hollow Sections. 132 mm deep, 132 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 132x132x6 at six metres each is 23.01 × 6 × 10 = 1,381 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: 29.31 cm² of steel at 7 850 kg/m³ is 23.01 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 4923 : 2017 gives 132x132x6 a mass of 23.01 kg per metre. Its printed cross-sectional area of 29.31 cm² agrees: 29.31 cm² of steel at 7 850 kg/m³ works out at 23.01 kg per metre.
138.06 kg. Mass per metre times length: 23.01 × 6. Ten such pieces come to 1381 kg.

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run against them, and the findings those checks produced — which rows disagree with themselves, which figures were superseded by amendment, and which could not be read — are QuickBOQ’s work, and so is this wording.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.
