I am trying to work out a conversion formula that would get me from size

of channel to weight per metre.

Details I have to hand is that the channel is 250 x 90 pfc

After much research I am told that the base of the channel is 250mm and is 15mm thick and the sides are 8mm thick(varying) and the channel is 1metre long. The answer is 35.5Kg per mtr. WhaT I want to know is how is that

worked out.
