let →u,→v and →w be three vectors in three-dimensional space, where →u and →v are unit vectors which are not perpendicular to each other and →u⋅→w=1,→v⋅→w=1,→w⋅→w=4. If the volume of the parallelopiped, whose adjacent sides are represented by the vectors →u,→v and →w is √2, then the value of |3→u+5→v| is
