I need to calculate the volume of a parallelepiped using the scalar triple product. I can do this if i have vectors. however instead we've been given 8 points which mark the corners. HELPPP this is the question:

Calculate the volume of the parallelepiped with vertices at:

(9,4,3), (7,12,2), (12,5,6), (3,-4,0), (10,13,5), (1,4,-1), (4,5,2) and (6,-3,3)
