Answer:
Step-by-step explanation:
Given is a point (2,4,5) in 3 dimension.
a) The projection of the point on xy plane would be with coordinate z=0 and same x,y coordinates
i.e. (2,4,0)
Similarly projection xz plane would be (2,0,5)
and projection on yz plane is (0,4,5)
If (2,4,5) is opposite vertex and faces are parallel to the coordinate planes
we would have the sides as xy plane yz plane and zx plane with extreme vertex as (2,4,5)
So all the 6 vertices would be
(0,0,0) (0,4,5) (2,0,5) (2,4,0) (0,4,0) (0,0,5) and (2,0,0),(2,4,0)
