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.
Calculate the total weight in tons for the following combination of quantities and sizes of rebar....
