Volume of the parallelopiped with its edges represented by the vectors $\hat i+\hat j, \hat i+2\hat j$ and $\hat i+\hat j+π\hat k$, is
Answer & explanation
Correct answer: option 1
Volume of the given parallelopiped is the absolute value of the determinant
$D=\begin{vmatrix}1&1&0\\1&2&0\\1&1&π\end{vmatrix}=π$
∴ Volume = $π$
