Thank you

Thank you
We need to know the density of the material the wire is made from. If the length is l, the volume is l x the cross section (use pi r squared).

Knowing the density, you can then have an equation in l, using density = weight divided by volume.

i was the worst one in math class. just didn't have it in my brain,
if the wire made of stainless steel 2.2. mm thick can you calculate for me the length

Post #2 tells you what to do. In particular, it tells you that the density is required before the calculation can be done.

Get the density and do what post #2 says. If you are stuck, show all your work and say where you are stuck.

5. lol. if i knew how to get the density i think i could be Einstein

anyway thanks much for trying to help

Here you go, Metals and Alloys - Densities

Let us know if you need help with teh calculation, but have a go yourself first, eh?
