Mental Imagery and Spatial Rotation Brain Teaser

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

mental rotation task

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).
