Answer 1

According to Given in question

Rebar size is No.4 # 2150 LF

Reabar size No. 6 # 1500 LF

Rebar size No. 8 # 1250 LF

Calculting:- Weight of rebar in tons

From given table allready is given weight of Rebar for 1 Rebar

Rebar No.4 Nominal weight 1 bar = 0.994 kg/m for 1 meter length bar

Then total weight for 2150 LF = 2150 * 0.994 = 2137.1 kg = 2.355 ton ------------------- A

Rebar No.6 Nominal weight 1 bar = 2.235 kg/m for 1 meter length bar

Then total weight for 1500 LF = 1500 * 2.235  = 3352.5 kg = 3.67 ton ------------------- B

Rebar No.8 Nominal weight 1 bar = 3.973 kg/m for 1 meter length bar

Then total weight for 1250 LF = 1250 * 3.973 = 4966.25  kg = 5.47  ton ----------------- C

Total weight of Rebar = 2.355 + 3.67 + 5.47 = 11.495 ton ANS.
