Show that veca.(vecbxxvec c) is equal in magnitude to the volume of the parallelopiped formed on the three vectors, veca,vecb and vec c

Volume of parallelpiped formed by vectors veca xx vecb, vecb xx vecc and vecc xx veca is 36 sq. units.

Valume of parallelpiped formed by vectors veca xx vecb, vecb xx vecc and vecc xx veca is 36 sq. units.

Valume of parallelpiped formed by vectors veca xx vecb, vecb xx vecc and vecc xx veca is 36 sq. units.

Show that if vecA. (vecBxxvec c)=0 , then vecA, vecB and vec c are coplanar .

If veca, vecb, vecc are mutually perpendicular vectors of equal magnitudes, show that the vector veca+vecb+vecc is equally inclined to veca, vecb and vecc .

If veca, vecb, vecc are mutually perpendicular vectors of equal magnitudes, show that the vector veca+vecb+vecc is equally inclined to veca, vecb and vecc

Three vectors veca, vecb, vec c are such that |veca|=3, |vecb|=2, |vec c|=6 , if each vector is perpendicular to the sum of the other two vectors, then the value of |veca+vecb+vec c| is -

If |veca|=2,|vecb|=3 and |vec(c)|=4 and each of veca,vecb,vec(c) is perpendicular to the sum of the other two vectors, then find the magnitude of veca+vecb+vec(c) .
