NOTE: The problem asks to cut the board into 10 equal parts, not into equal boards proportional to the original piece of wood.
Case 1: CANNOT stack wood on top of each other.
Assume the board 5 feet by 2 feet. If you made one horizontal cut in the center of the board 1 foot from each edge, and then made four vertical cuts at 1 foot apart, you would then have 10 equal pieces at 1' by 1' each. Time taken: 5 minutes for 5 cuts.
Case 2: CAN stack wood on top of each other.
The board is 5 feet by 2 feet. Cut the board long way 1 foot from the middle and the result is 2 boards 5 feet by 1 foot. Stack these two boards on top of each other. Then, cut the stack vertically one foot from the end now making 2 pieces of wood 1' by 1' and 2 pieces of wood 4' by 1'. Then, take the 2 pieces of wood 4' by 1' and stack them on top of each other. Cut vertically once in half, so you now result in 4 boards 2' by 1'. Finally, stack these 4 pieces of wood on top of each other. Cut once vertically and you now have 8 pieces of wood 1' by 1' (plus the 2 from earlier which now make 10). Time taken: 4 minutes for 4 cuts.

How do you cut a cake into 8 equal pieces in 3 cuts?
This is a trick question. Normally if you wanted to cut a cake into 8 equal pieces you would do so with more than 3 cuts. However, it is possible to do it in 3 cuts if you have a sufficiently long knife. By cutting the cake with two perpendicular cuts you can easily get 4 equal pieces. Then you rearrange these 4 pieces so that they are in a line, with all the pointy ends aligned in the same direction. Then you can cut all four pieces in half with one more cut. But it takes a long knife.Answer:Alternately two perpendicular cuts to make 4 equal pieces and a horizontal cut at the middle of the cake to make it into two equal layers each with 4 equal pieces.But if the cake has frosting on top, then the top pieces can't really be exactly equal to the bottom pieces which won't have frosting on top. Nonetheless, it's a good alternative. And not all cakes are frosted.
