Question

A cake should cut into 8pieces but in 3 cuts only you have to cut

Answer 1

Say, you are given a cake which you must share with 7 others. So, you must cut the cake into 8 pieces. But, you are only allowed to make 3 straight cuts. You cannot move pieces of the cake after the first cut.

Answer 2

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).
