Answer
$(0,2,0),(4,0,0),(4,2,0),(0,0,2),(0,2,2),(4,0,2)$.
Work Step by Step
1. Given vertices $(0,0,0),(4,2,2)$, we can find other vertices:
X-Y plane (z=0): $(0,2,0),(4,0,0),(4,2,0)$,
Y-Z plane (x=0): $(0,2,0),(0,0,2),(0,2,2)$,
X-Z plane (y=0): $(4,0,0),(0,0,2),(4,0,2)$,
2. Remove repeating points to get $(0,2,0),(4,0,0),(4,2,0),(0,0,2),(0,2,2),(4,0,2)$.
