Hello, I know the answer is v or x only but I want to know how to get to that answer. Please help.

3. Volume of Brillouin zone. Show that the volume of the first Brillouin zone is (27)³/V where Ve is the volume of a crystal primitive cell. Hint: The volume of a Brillouin zone is equal to the volume of the primitive parallelepiped in Fourier space. Recall the vector identity (×ā) × (axb) = c.(axb)ā.

How do you find the external forces' resultant and the application point?
