My very rough calculations using 85kg as an average adult weight, results in 153gr of iron
My problem is, that i dont have any expectations as to how heavy a longsword is but i'd assume it to be a lot heavier!
After further research it looks like the more appropriate number of humans needed to make an average longsword would be closer to 25.000
300 * 3g = 900g.
300 * 4,5g = 1350g

It's close enough, I'd say. OP's maths that is.
