37. The following is a cuboid whose one of the vertices is \( O (0,0,0) . P ( a , b , c ) \) is an edge on the space. Based on the above information, answer the following questions. (i) Find the coordinates of the feet of perpendicular from \( P ( a , b , c ) \) on the coordinate planes. (ii) If \( a =3, b =4 \) and \( c =5 \), find \( |\overrightarrow{A P}+\overrightarrow{B P}+\overrightarrow{C P}| \). (iii) If \( a = b = c \), find the unit vector perpendicular to \( \overrightarrow{O P} \) and \( \overrightarrow{C D} \). OR If \( a = b = c \), find the angle between any two diagonals of the cube..
