Hey. I’m having trouble with this work I’ve been set about structures. I understand some of it, which I’ll explain later, but I really need your help with it!(adsbygoogle = window.adsbygoogle || []).push({});

My task is to investigate different sized cubes, made up of single unit rods and justify formulae for the number of rods and joints in the cubes. For example, 2 by 2 by 2 cube, 3 by 3 by 3 cube etc etc etc…

I desperately need help on getting a formula to work this out. I know already, as my teacher gave us these results, that a 1 by 1 by 1 cube has the following:

8 Three-Joints ( as do all cubes)

0 Four Joints

0 Five Joints

0 Six Joints

and a 2 by 2 by 2 has:

8 three joints

12 four joints

2 five joints

1 six joints

I really need a formula in order to calculate how many joints a 3 by 3 by 3 has, and with that formula to use it on lets say a 55 by 55 by 55 cube.

All help would be appreciated!
