Three Cuts to Turn a Round Cake Into Eight Equal Slices

How can you cut a round cake three times to make eight equal slices?

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.
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).

First cut makes Two circles (inner circle will have 2/3 radius) and two more cuts perpendicular to each other will result in 8 equal pieces

First cut makes TWO halves. Place both halves one above another and make a cut making FOUR pieces. Place these four pieces one above other and cut them to make EIGHT equal size pieces.

The “correct” answer is to cut the cake in quarters (4 pieces) using 2 of the cuts – one horizontally down the center of the cake and the other vertically down the center of the cake. This will leave you with 4 pieces (or slices) of cake. Then, you can take all 4 pieces and arrange them in a stack that is 4 pieces high. Finally, you can just cut that stack of 4 pieces in half – using your third and final cut – and then you will end up with 8 pieces of cake!

You could think it as a donut with the hole filled in, so when you make a slice down the middle and two on the left and right going vertically, you have 8 slices because the hole is filled in. :)

Cut it vertically, then horizontally, then through the middle.

No need for cake stacking or cutting circles out of circles. Think of the cake as a cylinder. Slice the cylinder into quarters as you normally would cut a cake. Then, slice the cylinder into two cylinders by making a cut halfway between the top and bottom of the cake. You’re left with eight pieces of cake, all in the shape of a quarter circle half as tall as the original cake was.

Really? Slow thinkers? First. If you cut a 2 layer cake with icing on it, horizontally through the middle, the result is icing on the top 4 pieces and no icing on the bottom four. Not a fair shake for the last four cake eaters.

But what if it’s a Victoria sponge cake or any other type of cake with a messy middle?
