What are the properties of the diagonals of a cube?
The diagonals of a cube include face diagonals and space diagonals. Face diagonals connect opposite corners within the same face and are equal in length, measuring \\\\( \\\\sqrt{2} \\\\) times the side length. Space diagonals connect opposite vertices through the interior, measuring \\\\( \\\\sqrt{3} \\\\) times the side length. All space diagonals are equal.
