If a = 2i + 3j, b = I + j + k, c = `lambda` I + 4j + 2k are the edges of a parallelopiped of volume 2 cubic units, then a value of `lambda` is

If vec a = -2i+3j, vec b = i+j+k, vec c = lambda i + 4j +2k are the three coterminal edges of parallelepiped of volume 2 cubic units, then a value o f gamma is

If a = 3i - 2j + k, b = 2i - 4j - 3k, c = -i + 2j + 2k then a + b + c =

If a = i- 2j + k, b = 2i + j - k, c = 4i + 4j + 3k then |(a xx b) xx c| =

If a = i + j - 2k, b = -i + 2j + k, c = i - 2j + 2k, then a unit vector parallel to a + b + c =

The volume of parallelopiped with edges I, I + j, I + j + k is

If I - 2j, 3j + k and lambda I + 3j are coplanar. Then lambda =

Consider the parallelopiped wide sides a = 3i + 2j + k, b = I + j + 2k and c = I + 3j + 3k then the angle between a and the plane containing the face determined by b and c is
