We all know what a ring doughnut looks like. Technically it is a Toroid, but the ring doughnut is so ubiquitous that toroids are described as doughnut-shaped rather than the other way round.
Regardless of how you describe it, the challenge this week is to cut a doughnut into as many pieces as possible using only three straight cuts. The pieces do not have to be the same size or the same shape; you just have to get as many as you can.
How many pieces can you produce?
