The position vectors of the four angular points of a tetrahedron \( O A B C \) are \( (0,0,0),(0,0,2),(0,4,0) \) and \( (6,0,0) \), respectively. A point \( P \) inside the tetrahedron is at the same distance ' \( r \) ' from the four plane faces of the tetrahedron. Then, the value of \( 9 r \) ishttps://bit.ly/YTAI_PWAP https://www.pw.live
