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! 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!
