Question

How can you cut a round cake into 8 equal pieces with only 3 cuts of the knife?

Answer 1

Cut #3 – Through the middle edge of the cake slicing all four of the pieces in equal halves, leaving eight equal slices (four equal tops and four equal bottoms). Cut #1 – Down the center of the cake (vertically) leaving two equal halves. Cut #2 – Across the center of the cake (horizontally) leaving four equal slices.
