    Understanding Coplanar Parallelepiped in Vector Algebra

    I have just completed a question in which I have determined: (axb).c = 0 = det [a,b,c] Where: a = (1,1,2) b = (2,3,4) c = (1,-2,2) With some googling, I established this meant the parallelepiped to be coplanar but I'm not sure exactly what this means. If anyone could offer me some...
