Hidden Faces Of A line Of Cubes

Hidden Faces Introduction: I need find out a formula for the number of hidden and visible faces of a line of cubes placed on a flat table. E.g. for a line of three cubes there is a total of 18 faces, 11 of them are visible and 7 of them are hidden. I will need to find a formula for a quicker way of working this out. I will draw the cubes and write up tables to …showed first 75 words of 477 total…

…showed last 75 words of 477 total…at how many faces were hidden in the end two and then looked at the number of hidden faces in the centre cubes, I then devised the above formula. Conclusion: I thought my investigation went very well. I found my formulas quite quickly and I was able to write them up. I will now try to apply some of the same techniques used in this investigation to my extension work, Hidden Faces of a Cuboid.
