Find the volume of the parallelepiped whose coterminous edges are represented by the vectors:
Formula: -
and
then,
Given: -
we know that the volume of parallelepiped whose three adjacent edges are
is equal to 
.
we have
now, using
= 1(1 – 2) – 1( – 1 – 1) + 1(2 + 1)
= 4
therefore, the volume of the parallelepiped is
= 4 cubic unit.
