answer is 14.3 Kg.
MS Channel Weight: 100mm(length)*50mm(width)*5mm(thick)*.000785=19.625 Kg
100mmx50mmx5mmx0.000785x100m=1962kg
75*40
divide the beam into three rectangles, calculate the area of each rectangle and multiply it by length. then you get the volume of beam & finally multiply it by density
12.7 kg / m
MS Channel Weight: 100mm(length)*50mm(width)*5mm(thick)*.000785=19.625 Kg
The weight of MS channel 100x50x5mm is 920Kg in 100Mtrs. ashim bhowmick

125*65 c channel calculate
If it section is a rolled like beam,channel,square,angles&flat. weight=Length x unit weight unit weight of this section is=123kg/m^3 If it is plate or sheet weight=Length x width x thickness x 7.85(sp.gravity of steel)
12.7 kg / m
To calculate the weight: Height x Width x Length x 2.5
It is not possible to calculate weight just from length, width and/or height. (These can give you volume and area, but not weight). For weight, you need to know "how heavy it is per this amount of stuff" is - e.g "3 grams per square cm" or "6 tonnes per inch".

You can calculate the height of a fence, its length, mass, weight or many other characteristics. But you cannot calculate a fence.
