Question: Calculating volume of parallelepiped

Ive tried several commands, but none of them will give me a response

Here are the points im working with:

u = (2, -3, 1), v = (-4, 3, 3), w = (2, 4, 6)

And here are the several commands ive tried to use, with "with(LinearAlgebra), with(geom3d)" implemented before:

1. 

volume([2, -3, 1], [-4, 3, 3], [2, 4, 6], parallelepiped)

> with(plots, display);
> volume;
display(parallelepiped, axes = normal, scaling = constrained, orientation = [-50, 80])
 
2. 
volume(pp, point(A, 2, -3, 1), point(B, -4, 3, 3), point(C, 2, 4, 6))
 
I've tried them already but there giving me errors, so i'd like to know the right way to compute the area of a parallelepiped with those three vectors
All help is greatly appreciated
Thanks!
