Can you cut a cake fairly to solve this middle school math problem?

6 cuts. Didn't say that she had to serve all of the cake.
If all of the cake is to be served, 10 cuts.

Your'e right.  I didn't make that clear initially so I went back and revised it while you weren't looking.

How big a piece were you thinking of giving each of us?  Would the shape of each piece be the same?  I can also do it in 6 cuts without serving up all the cake (while also making the pieces any size you like from tiny up to 1/8 of the cake each).  I wonder if we used the six cuts the same way.  Come to think of it, if I cut the entire cake into 8 equal pieces this way, I can do it with just 4 cuts.
