A) \[80\]
B) \[120\]
C) \[160\]
D) \[40\]
Correct Answer: A
Solution :
Given, volume of parallelepiped \[[\vec{a}\,\vec{b}\,\vec{c}]=0\] \[\therefore \] Volume of parallelepiped \[=[\vec{b}+\vec{c}\,\,\,\,\vec{c}+\vec{a}\,\,\,\,\,\vec{a}+\vec{b}]\] \[=2[\vec{a}\,\,\vec{b}\,\,\vec{c}]\] \[=2\times 40=80cu\,unit\]You need to login to perform this action.
