I have done this so far, would anyone please verify this.

(2,0,0)(0,9,6)

(0-2, 9-0, 6-0)

=(-2,9,6)

(-2,9,6)(0,0,3)

=(2,-9,-3)

(2)(-9)(-3)=54 cm^3

Therefore volume is 54 cm^3

**Reiny**, Friday, March 23, 2012 at 12:04am54 cm^3 is the correct answer

I do it differently:

if given 3 vectors a, b, and c

volume of parallelepiped

=| a . (b X c) |

(2,0,0) X (0,0,3) = (0, -6, 0)

volume = |(0,9,5) . (0,-6,0) |

= |0-54+0| = 54
