Birthday Cake Puzzle

Qs :

A birthday cake has to be equally divided into 8 equal pieces in exactly 3 cuts.

Determine the way this division can be possible.

Solution :

Start slicing the cake horizontally down the centre, followed by making another division vertically through the centre.

The two divisions made across horizontal and vertical directions will give  4 equal pieces of the cake.

In the final step, stack the 4 pieces one above the other. Then make the third division, splitting the stack into half. This gives you the 8 equal pieces of cake.
