1. Compute the cross product \(\vec{v} \times \vec{w}\):
\vec{v} \times \vec{w} = \langle 5, -11, -14 \rangle
2. Compute the dot product \(\vec{u} \cdot (\vec{v} \times \vec{w})\):
\vec{u} \cdot (\vec{v} \times \vec{w}) = 20
3. Take the absolute value of the result to obtain the volume:
V = \left| 20 \right| = 20
Answer:
V = 20
