Final answer:
The maximum number of sides a cross-sectional shape of a cube can have is 6, occurring when the cube is sliced diagonally through opposite edges.
Step-by-step explanation:
When slicing a cube, the maximum number of sides that the cross-sectional shape could have depends on the orientation of the slice:
- If sliced perpendicular to its base, the cross section is a square with 4 sides.
- If sliced parallel to its base, the cross section is also a square with 4 sides.
- When sliced diagonally (along a plane that intersects the opposite edges of the cube), the cross section can be a hexagon with a maximum of 6 sides.
Therefore, the maximum number of sides a cross section can have when slicing a cube is 6, which occurs with a diagonal cut through the cube.
