An air bubble is trapped inside a glass cube of any $30 c m$ . Looking through the face $ABEF$ the bubble appears to be normal at a distance $12 c m$ from this face and when seen from the opposite face $CDGF$ , it appears to be at normal distance $8 c m$ from $CDGF$ . Find refractive index of glass and also the actual position of the bubble.
