The edges of a parallelopiped are of unit length and are parallel to non-coplanar unit vectors `vec a, vec b, vec c such that `hat a.hatb=hatb .hatc=hatc.hata=1/2`. Then, the volume of parallelopiped is

The edges of a parallelopiped are of unit length and are parallel to non coplanar unit vectors hata,hatb,hatc such that hata.hatb=hatb.hatc=hatc.hata=1/2 Then the volume of the parallelopiped is (A) 1/sqrt(2) (B) 1/(2sqrt(2)) (C) sqrt(3)/2 (D) 1/sqrt(3)

The edges of a parallelopiped are of unit length and a parallel to non-coplanar unit vectors hata, hatb, hatc such that hata.hatb=hatb.hatc=hatc.veca=1//2 . Then the volume of the parallelopiped in cubic units is

The edges of a parallelopiped of unit length are parallal to non-coplanar unit vectors widehat a,hat b,hat c such that widehat a.hat b=hat b*hat c=hat c.widehat a=1/2, then the volume of parallelopiped whose edges are widehat a xxhat b,hat b xxhat chat c xx widehat a is
