Question

how can we cut a cake into 8 parts by 3 straight cuts

Answer 1

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 thecake slicing all four of the pieces in equal halves, leaving eight equal slices (four equal tops and four equal bottoms).

Answer 2

• Cut the cake with 2 perpendicular cuts through the center, then make a horizontal cut at half the height of the cake.
• It is not fair regarding topping, but you have 8 pieces.
