Introduction

Introduction This report is about working out the formula to a hidden faces equation, I will find the nth term, put my results into a table and, figure out if the formula works. ...read more.

Middle

say 100 cubes rather than do trial and error, or put cubes together and work it out. I will record my results in a table that has 3 columns, 1, number of cubes 2, number of hidden faces 3, the formula I will prove this by picking a low number like..1, and a really high one like 100 and test my formula on it. ...read more.

Conclusion

Hypothesis I predict that the formula is 3n-2. Number of cubes Number of hidden faces Formula 1 1 3n-2 2 4 3N-2 3 7 3N-2 4 10 3N-2 5 13 3N-2 6 16 3N-2 7 19 3N-2 8 21 3N-2 9 24 3N-2 My formula works because 3n-2 = 3X1-2 31=3 3-2=1 it works with all numbers 3n-2 = 3X6-2 3X6=18 18-2=16 ...read more.

Q or H for X, which will represent all or any of the shapes. So the formulas I have are: T=P+2D-2, Q=P/2+D-1 and H=(P+2D-2)/4. I think that to get my universal formula, I need to have all these three in the same 'format'.
