Mark (√) against the correct answer in the following:
If the volume of a parallelepiped having 
and 
as conterminous edges, is 216 cubic units then the value of λ is
Given volume of the parallelepiped is 216 cubic units
Given 
And 
=
are the coterminous edges of the parallelepiped.

216
⇒216=
⇒ 216=5[21-(-2

⇒ 216= 105 +10 λ +112 -4 λ -11
⇒ 216-105-112+11=6 λ
⇒ 6 λ =10
