Use the Given Transformation to Evaluate the Integral Where $R$ Is the Parallelepiped Bounded by the Planes

Use the given transformation to evaluate the integral.
- $$\begin{aligned}u = & 2 x + y - z , v = - x + y + z , w = - x + y + 2 z \\& \iiint ( 2 x + y - z ) ( z - x + y ) ( 2 z - x + y ) d x d y d z\end{aligned}$$
where $R$ is the parallelepiped bounded by the planes $2 x + y - z = 2,2 x + y - z = 3 , - x + y + z = 2 , - x + y + z = 6$ , $- x + y + 2 z = 2 , - x + y + 2 z = 7$
