The origin $O$ of the world coordinate system is chosen at the center of the cube and the cube has

edges of $2$ lengths. Thus, for example, the coordinates of point A are $1,-1,-1$

Exercise $1-$ do a set of input data for the cube to get a plot like Fig. $26$ and$/$or Fig$\mathrm{.}27$: $($Using Excel$)$
