Eli5: Why is it that there are multiple copper wires inside an electric cable and why are they coiled?

It's good to have a thick wire, so electric current can easily flow through it. But if it was just a solid chunk of copper, it wouldn't bend easily.

Putting multiple copper wires in close proximity makes the cable easy to bend while also letting a lot of current through.
