You've made the finals of the Science Olympics! As one of your tasks, you're given 1.1 g of copper and asked to make a wire, using all the metal, with a resistance of 2.0 (ohms). Copper has a density of 8900 kg/m^3.

What length will you choose for your wire?

What diameter will you choose for your wire?

Please help me out. I got 3600 m for the length and .0062mm in diameter. It's wrong but I have no idea what I did wrong. Please help with some details. it would be much appricated!
Thank you in advance!
