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.

and showing faces, but instead use the dimensions of a cuboid to work out the total number of hidden faces. This rule works because all you are doing is taking away the total amount of showing faces away from the total amount of faces on every cube in a cuboid.

For a cube sized 3 x 5 x 9... The number of cubes with three faces painted will be 8. The number of cubes with two faces painted will be 44. 4(3 - 2) + 4(5 - 2) + 4(9 - 2)

This places the idea that there is a individual neural structure that is used purely for the discrimination and recognition of faces alone. Farah (1994 as cited in Eysenck and Keane, 2001) carried out a study in which he used a patient suffering from prospagnosia called LH.

So I could call this xz. This could be preceded by y as it equals 1. So I will find out more in the next arrangement. In the next arrangement, x=3, y=1 and z=2. This time hxy=6, hyz=8, and hxz=6. Looking at the earlier expressions I can see that 2xy still looks good although 2 could

2. Investigate the number of hidden faces when cubes are joined in different ways.

a/many cube, by subtracting the total number of faces from the total number of visible faces, which will give us the total number of hidden faces. To check whether this equation is correct we can add the total number of hidden and seen faces together so that it can give us the total number of faces.
