Hi everybody! I am trying to solve the question for a long time: [*4.12 Harder] Find out the maximum number of pieces we can get by making a given* *number of flat (that is planar) cuts through a solid block. It is not the same* *answer as we calculated for straight-line cuts of a flat piece of paper.* I find out that this function has the following results: f 0 = 1 f 1 = 2 f 2 = 4 f 3 = 8 That is, from 0 to 3, the flat cuts all the pieces in two other pieces, so the number of pieces is doubled. But, starting from f 4, the flat can not cuts all the pieces, in case of f 4, the flat can cut 6 out of the 8 pieces, resulting in 12 pieces plus 2 pieces 2 = 14 pieces. But I can not reach a general case. Can anybody help me to find out the solution? Thank you very much!
