What do you call a three-dimensional hexagon? If you’re not sure, don’t worry – you’re not alone. Even those familiar with geometry may not be aware of the name for this shape. It’s actually called a hexagonal prism, and it’s a shape that appears in everything from architecture to chemistry.
When thinking of a hexagon, you might picture a flat, two-dimensional shape with six sides. However, a hexagonal prism takes that classic shape and extrudes it vertically, forming a three-dimensional figure. It’s created by taking a hexagon and drawing lines perpendicular to each side, then connecting those lines to form a solid figure.
So why is it important to know what a hexagonal prism is called? Well, for starters, it can help you better understand and identify shapes in the world around you. Additionally, it’s a shape that’s commonly used in construction and manufacturing, which means that understanding its properties can be useful for designers and engineers alike. Whether you’re a student of geometry or just someone who’s curious about the world, it’s helpful to have a name for this fascinating three-dimensional shape.
Naming conventions for 3D shapes
When it comes to naming 3D shapes, there are a variety of conventions that can be used to identify and differentiate different shapes. In general, these naming conventions are based on the number of faces, edges, and vertices that a given shape has. Here are some of the most commonly used naming conventions for 3D shapes:
- Prisms: Prisms are named based on the shape of their base and the number of sides on that base. For example, a prism with a triangular base is called a triangular prism, while one with a pentagonal base is called a pentagonal prism. The number of sides on the base is usually included in the name, so a prism with a square base would be referred to as a square prism or a 4-sided prism.
- Pyramids: Like prisms, pyramids are named based on the shape of their base. However, instead of having a flat top like a prism, pyramids have a single point. Pyramids are typically named after the shape of their base as well as the number of sides on that base. For example, a pyramid with a square base is called a square pyramid or a 4-sided pyramid.
- Platonic solids: Platonic solids are 3D shapes that are regular polyhedra, meaning that all of their faces are the same regular polygon (i.e., they have equal side lengths and angles). There are five platonic solids: the tetrahedron (4 faces), cube (6 faces), octahedron (8 faces), dodecahedron (12 faces), and icosahedron (20 faces). These shapes are named based on the number of faces they have.
- Hexagons: Hexagons are 6-sided polygons that can be used as the base for 3D shapes as well. There are several 3D shapes that are based on hexagons, including the hexagonal prism and the hexagonal pyramid. However, there is no specific term for a hexagonal 3D shape in general (i.e., without specifying whether it is a prism or a pyramid).
Definition of 3D Hexagon
A hexagon is a polygon with six sides and six angles. In a three-dimensional plane, a hexagon is referred to as a 3D hexagon. A 3D hexagon is a six-faced figure that is enclosed by six sides, each of which forms a 120-degree angle with its adjacent faces. The 3D hexagon is a regular polygon and has six congruent sides and angles.
Types of 3D Hexagons
- Regular 3D Hexagon – Each of the six sides and angles is congruent to each other, and all three-dimensional angles are congruent and equal to 120 degrees.
- Irregular 3D Hexagon – Unlike the regular hexagon, all six sides and angles in an irregular 3D hexagon are not necessarily congruent.
- Convex 3D Hexagon – This type of hexagon has all its internal angles less than 180 degrees.
Properties of 3D Hexagons
A 3D hexagon has several distinctive properties, some of which are listed below:
- A 3D hexagon has 12 edges and eight vertices.
- The sum of all internal angles of a 3D hexagon is equal to 720 degrees.
- The three-dimensional figure has six faces, each of which is a regular hexagon.
- The total surface area of a 3D hexagon is the summation of the area of all its six faces.
Calculating the Area and Volume of a 3D Hexagon
The area and volume of a 3D hexagon can be determined by using a set of tables or formulae. These formulae can vary depending on the dimensions of the hexagon. For example, if the length of the hexagon is known, we multiply it by its height and divide the result by two to find its area.
| Dimension | Formulae |
|---|---|
| Surface area of a regular 3D hexagon | $6a^2$ |
| Volume of a regular 3D hexagon | $\frac{3\sqrt{3}}{2}a^3$ |
| Perimeter of a regular 3D hexagon | $6a$ |
It is important to note that these formulae apply to regular 3D hexagons, and not to irregular hexagons.
