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

Hmmm, how about 10 cuts.
Step 1: 2 cuts to shave off the frosting from two opposite sides of the cake.
Step 2: 4 cuts through the cake parallel to the first two cuts to divide the cake, the frosting on top, and the fronting on the other two sides of the cake into 5 equal portions.
Step 3: 4 more cuts to divide the frosting removed in step 1 into 5 equal portions.
That seems like too many cuts for an elegant solution, but is the best I have at the moment.
