I have been given a piece of course work for university, see attachment. I have completed questions 1 and 2 but am completely stumped with question 3 as the 3d stuff has thrown me off and dont even know how to get the cubes cordinates in 3d for excel.

I sure this is childs play for some of the experts on here but a little help with the cordinates and transformations will be much apreciated.

thank you
