The odd one out is the cube which is a 3D shape whereas the rest are 2D shapes if that is your question.
An equilateral triangle, a square, a hexagon, a pentagon, a decagon, an octagon, the list goes on and on.
Octagon.

Why
We have the triangle (3-sided), square (or quadrilateral, 4-sided), pentagon (5-sided), hexagon (6-sided), heptagon (or septagon, 7-sided), octagon (8-sided), nonagon (9-sided) and decagon (10-sided) to get you started.
The shape that does not belong is "Cube." All the other options (Square, Triangle, Pentagon, Hexagon, Octagon) are two-dimensional shapes, while a Cube is a three-dimensional object.

They are a miscellaneous collection of polygons.

Octagon.
Of the four shapes mentioned, the octagon has the most sides. Square has 4 sides, hexagon has 6, pentagon has 5, and the octagon has 8.
The odd one out in the group is "cube." All the other shapes (square, triangle, pentagon, hexagon, octagon) are two-dimensional polygons, while a cube is a three-dimensional geometric shape. This distinction sets the cube apart from the rest of the group.
