If you're going to break the mirror into pieces, it doesn't matter what shape it is. You just care about covering the surface area of the globe, which is 4*pi*r^2. Which is approximately
12.5*r2
As an example, then if it were to be a square mirror, you'd need one with sides approximately 3.5r
Right on, Kim!
The shape does not matter but the size should be at least the surface of the ball.
Take a look at the beautiful disco balls in the window of the Men's Warehouse in Manhattan. Some of them are not even balls.
