A cone is the solid that has one face.
The question "Which solid has one face?" is answered by examining different 3D shapes and identifying those possessing only a single face. A face, in geometric terms, is a flat surface on a solid. Below is an examination of solid shapes which includes a shape that fits the criteria.
Understanding Solid Shapes
Before determining the solid shape with one face, let's consider the basic components of geometric solids. These include:
- Faces: Flat surfaces that make up the solid shape.
- Edges: Lines where two faces meet.
- Vertices: Points where edges meet (corners).
Identifying the Solid with One Face
According to the reference, a cone has one face, but no edges or vertices. This face is specifically a circle. Other common 3D shapes include cubes, spheres, and cylinders, which are not considered to have just one face.
| Solid Shape | Number of Faces |
|---|---|
| Cone | 1 (circular) |
| Cube | 6 |
| Sphere | 0 (a curved surface) |
| Cylinder | 3 (2 circular faces and 1 curved face) |
Examples
- A typical ice cream cone is a real-world example of a cone that has only one face.
- Party hats are also often shaped like cones.
Therefore, the shape that meets the criteria of having one face is a cone.
