Find the valume of a parallelepiped having three coterminus vectors of equal magnitude `|veca|` and equal inclination `theta` with each other.

Find the volume of a parallelopiped having three coterminus vectors of equal magnitude |a| and equal inclination theta with each other.

If V is the volume of the parallelepiped having three coterminous edges as veca,vecb and vecc , then the volume of the parallelepiped having three coterminous edges as vecalpha = (veca.veca)veca+(veca.vecb)vecb+(veca.vecc)vecc , vecbeta=(vecb.veca)veca+(vecb.vecb)+(vecb.vecc)vecc and veclambda=(vecc.veca)veca+(vecc.vecb)vecb+(vecc.vecc)vecc is
