Calculating Electron Flow in a Copper Wire

[sdkl84]

Homework Statement

An electric current of 6 A flows through a 5 mm diameter copper wire with a length of 10 m.
What is the average number of electrons that flow through a cross section of the wire per second?

Homework Equations

I=Q/t or I=dQ/dt Maybe, I am not sure

The Attempt at a Solution

1 Coulomb = 6.24e18
6*6.24e18
3.744E19 e/s

Weird as the diameter and length are unnecessary. But thumbs up for solving it!
