(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the volume of the parallelepiped with adjacent edged PQ, PR, and PS.

P (-2,1,0)

Q (2,3,2)

R (1,4,-1)

S (3,6,1)

2. Relevant equations

Volume = PQ . (PR x PS)

3. The attempt at a solution

I first found the vectors PQ, PR and PS. Then I did the cross product of PR x PS and then did the dot product of PQ (dot) PR x PS. I got an answer of 6, but the answers in the back of the book says 16. Did I do it wrong? or is the book wrong?
