Hello everyone

could u plz help me to solve this question :

Use the scalar triple product to find the volume of the parallelopiped with vertices at

(−2,0,0),(2,0,0),(0,2,0),(4,2,0),(−1,1,4),(3,1,4), (1,3,4),(5,3,4) ?

thank u

thanks a lot honey

do u mean i have to choose 3 vectors a , b and c then apply in V??

for example: a=(2, 0,0) , b=(0, 2 ,0) c=(5,3,4) like that or not?

could u plz give example? I'm really very stack

thank u - Oct 3rd 2010, 04:20 AMHallsofIvy
No, those are points not vectors. Use the vectors

**from**(2, 0, 0) to three "adjacent" points. ("Adjacent" meaning there is an edge of the parallelpiped between the point and (2, 0,0).) - Oct 3rd 2010, 06:18 AMessence
ok it's clear now thanks a lot honey
