I need 200 feet of copper wire for a project but can’t tell from the description how long this is. Is it at least 200 feet long?

should be approximately 800 ft of 30AWG in a 4oz (1/4lb) spool. There are charts online that give feet/lb for all the wire gages if you want to confirm.

How long is the wire?

Good Question, not sure why they do not include this info on the web site. 20awg magnet wire is 3.1lbs per 1000ft or 0.0031 lbs per foot. The roll is 4oz or 0.25lbs so it should be ~80.6 feet.

What length of wire is on the spool?

This is in the description: Magnet wire is copper wire that coated with a thin layer of insulated enamel.This 28AWG magnet wire is 4 ounces(527 feet). The copper strands conducts,the insulation is made from modified Polyester with a Polyacrylamide overcoat,and protects the coiled wire from short-circuiting.

Is this single strand copper wire or multiple strands?

Single strand enameled. You don't even need pliers to remove the insulation, just a really hot soldering iron tip.
