3D Shapes : Vocabulary and Pronunciation guide

Three-dimensional shapes are not only useful in mathematics but also in everyday life too. Understanding their qualities and pronouncing their names correctly is critical for good communication and academic performance. So, in this article, we will dig into the realm of 3D shapes, covering their vocabulary, pronunciation, and significance. Let’s begin our educational trip!

The significance of 3D shapes

First of all, let’s explore three-dimensional forms, or 3D shapes. These objects have three dimensions: length, width, and height. In comparison to 2D forms, which only have length and breadth, 3D things are substantial and occupy space. In other words, 3D shapes are tangible and have volume. Moreover, they frequently appear in our daily lives and are used to create a variety of constructions and styles.

Vocabulary List

Below is a comprehensive list of 3D shapes vocabulary , along with their accurate pronunciations and brief explanations. So , let’s explore the diverse world of geometric figures:


Cube: 3D form that have six equal square faces, straight edges, and right angles at each corner.

Example: Box and dice.



Parallelepiped: 3D form that resembles a stretched-out box. It has six faces all of which are parallelograms.

Example: Bricks.



Sphere: A completely round three-dimensional form with all points on its surface identical distance from the center.

Example: Ball.



Cylinder: Three-dimensional form that looks like a tube with round ends.

Example: Can and pipe.



Cone: Three-dimensional structure with a circular bottom and a point on top.

Example: Ice cream cone.



Torus: 3D form that has a hole in the middle and a circular body surrounding the hole.

Example: Doughnut.



Octahedron: 3D form that has eight triangular faces, six vertices (points), and twelve edges (sides).



Dodecahedron: Three-dimensional shape that has twelve flat pentagonal shaped faces.


Pentagonal Prism

Pentagonal Prism: 3d form with two flat pentagonal faces on top and bottom joined by five rectangular faces on the sides.


Triangular Prism

Triangular Prism: 3D form that has a stack of triangles on each side. It has two triangular bases joined by three rectangular sides.

Example: Tent.


Hexagonal Prism

Hexagonal Prism: 3D form with a stack of triangles on each side. It is made up of two triangular bases connected by three rectangular sides.

Exemple: Hexagonal nut.



Frustum: Three-dimensional object that has a hole in the middle and is formed by rotating a circle around an axis in 3D space.

Example: Bucket.



Pyramid: Three-dimensional shape with a flat base and triangular sides that meet at a point on top. It looks like a pointed tower.


Pentagonal Pyramid

Pentagonal Pyramid: 3D shape with a flat, a pentagonal base and five triangular sides that come together to form a point at the top.


Hexagonal Pyramid

Hexagonal Pyramid: Three-dimensional form with a six-sided hexagonal base and six triangular sides that meet at a point on top.



Ellipsoid: 3D form that’s smooth and symmetrical, and you can create it by rotating an ellipse (a stretched circle) around one of its axes.

Example: Egg.


In conclusion , This 3D Shapes Vocabulary and Pronunciation Guide has offered a thorough grasp of three-dimensional geometric forms. In addition, These shapes provide the cornerstone of geometric studies, ranging from the simplicity of cubes and spheres to the intricacy of dodecahedrons and icosahedrons.
