A) 4
B) 3
C) 2
D) 8
Correct Answer: D
Solution :
Volume of parallelopiped \[V=[\mathbf{a}\,\mathbf{b}\,\mathbf{c}]\] \[\therefore \,\,V=\left| \,\begin{matrix} 1 & -1 & 1 \\ 2 & -4 & 5 \\ 3 & -5 & 2 \\ \end{matrix}\, \right|\] \[V=1(-8+25)+1(4-15)+1(-10+12)\] V \[=17-11+2=8\] unit.You need to login to perform this action.
