If vector OA, vector OB, and vector OC are three edges of a parallelpiped where O is (0,0,0), A is (2,4,-2), B is (3,6,1) and C is (4,0,-1) find the coordinates of the other vertices of the parallelpiped.

for this q, i am having trouble drawing the diagram of the parallelpiped

Currently though, I have the following possibilities.. (there are only 3 right?)

D(5,10,0)<<< DB//CA

D(3,-2,0)<<<CB//DA

D(1,10,0)<<<CB//AD
