The shape that has no surface is a point.
A point is a fundamental concept in geometry that represents a specific location in space. It has no dimension, meaning it has no length, width, or height. Therefore, it cannot have a surface area.
Think of it like this:
- A line has one dimension, length.
- A square has two dimensions, length and width.
- A cube has three dimensions, length, width, and height.
A point, however, has zero dimensions, making it a dimensionless entity. Consequently, it cannot have a surface.
