I have this number that I just wanted to be sure how to do. They give me a Parallelepiped with corners lettered from A to H. Then the question is:
In a certain orthonormal reference, the coordinates of points A, B, D and E are respectively
Calculate the coordinates of point C in that same reference.
I determined that the coordinates for C are (3,4,2) but I have no idea how one goes to calculate that. I'm looking for a method to resolve this number.
