Let \( ABCDEFGH \) be a cube and let \( XY \) be a line where:
\begin{align*}
X&\text{ lays on a ray }CB\text{ and }|CX|=1.5|BC|,\\
Y&\text{ lays on a ray }EH\text{ and }|EY|=1.5|EH|
\end{align*}
(see the picture). The points of intersection of the line \( XY \) with the surface of the cube lay:
on the sides \( ABFE \) and \( DCGH \)
on the sides \( EFGH \) and \( ABCD \)
on the side \( ABCD \) and the edge \( HG \)
on the edges \( HG \) and \( AB \)
