Here’s a fun puzzle that a friend gave me over dinner a few days ago …
How do you cut a cake into eight equal pieces with only three cuts?
the cake in the puzzle is not necessarily the one pictured below
You have to use your mental rotation and mental imagery skills to visualize the answer for this puzzle. In doing so, you are using your visual cortex in the occipital lobes, your somatosensory cortex in your parietal lobes, and your executive functions in your frontal lobes to help create and evaluate your hypotheses.
Answer: Use two cuts to cut the cake into four equal pieces. Use your third cut to cut the four pieces in half horizontally (perpendicular to the first two cuts).
