Find the volume of the parallelepiped whose coterminous edges are represented by the vectors:

Formula : -


(i) ifandthen,


(ii)


Given: -



we know that the volume of parallelepiped whose three adjacent edges are



we have



now, using



= 2( – 4 – 1) – 3( – 2 + 3) + 4( – 1 – 6)


= – 35


therefore, the volume of the parallelepiped is
