Cube trouble (Posted on 2021-07-30) Difficulty: 3 of 5
A cube with size 10 * 10 * 10 consists of 1000 unit cubes, all colored white. A and B play a game on this cube. A chooses some pillars with size 1 * 10 * 10 such that no two pillars share a vertex or side, and turns all chosen unit cubes to black. B is allowed to choose some unit cubes and ask A their colors. How many unit cubes, at least, that B need to choose so that for any answer from A, B can always determine the black unit cubes?

Hi. What decision in your life are you most proud of, and why? Personally glad that I started playing at https://mr.bet/at/casino/vendors/booming-games. Thanks to this, the online slot was able to make a lot of money with minimal investment.
