Three Dimensional Shapes – Definition With Examples

What Are Three-Dimensional Shapes?

In geometry, a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height. Unlike two-dimensional shapes, three-dimensional shapes have height, which is the same as thickness or depth. Three dimensional is also written as 3-D and hence, these figures are commonly called 3–D shapes too. All 3-D shapes occupy space, which is measured in terms of volume.

Examples of Three-Dimensional Shapes

A cube, rectangular prism, sphere, cone, and cylinder are the basic 3-dimensional shapes we see around us.

Real-life Examples of Three-Dimensional Shapes

3-D shapes can be seen all around us. We can see a cube in a Rubik’s Cube and a die, a rectangular prism in a book and a box, a sphere in a globe and a ball, a cone in a carrot and an ice cream cone, and a cylinder in a bucket and a barrel around us. 

Real-life Examples of 3-D Shapes

Attributes of Three-Dimensional Shapes

There are three attributes of a three-dimensional figure: face, edge, and vertex. Let’s understand three dimensional shapes and their properties in detail.

Attributes of 3-D Shapes

Face: Each single surface, flat or curved, of the 3-D figure is called its face.

Edge: The line, where two faces of the 3-D figures meet, is called its edge.

Vertex: Each corner, where three faces of 3-D figures meet, is called its vertex. Vertices are the plural of the vertex.

List of Three-Dimensional Shapes

Here’s a list of the names of three-dimensional shapes with their pictures, and attributes.

Net of Three-Dimensional Shapes

A net is a pattern made when the surface of a 3-D figure is laid out flat, showing each face of the figure.

3-D figures can have more than one net pattern. Net of a few 3-D figures is shown below:

Fun Facts:
All three-dimensional shapes are made up of two-dimensional shapes.

Difference between 2-D Shapes and 3-D Shapes

Let’s differentiate between 2-D and 3-D shapes by understanding two dimensional and three dimensional shapes and their properties.

1Which shape has 2 flat faces and one curved face?

Cylinder
Sphere
Cone
Cuboid
CorrectIncorrect
Correct answer is: Cylinder
Cylinder has two flat faces which are a circle in shape and one curved face.

2How many square shapes does the net of a cube have?

4
6
8
10
CorrectIncorrect
Correct answer is: 6
Cube has 6 faces that are squares. So, the net of the cube will have 6 square shapes.

3Which of the following has no edge?

Cone
Cylinder
Cuboid
Sphere
CorrectIncorrect
Correct answer is: Sphere
Sphere has one face. So it has no edge.

4Which of the given shapes is NOT a 3-D shape?

Trapezoid
Prism
Pyramid
Cube
CorrectIncorrect
Correct answer is: Trapezoid
Trapezoid is a 2-D shape with four sides with one pair of opposite sides parallel to each other and the other two sides of it are non-parallel.

Frequently Asked Questions

Cube, cuboid, cylinder, sphere, cone, prism, and pyramids.

Three-dimensional shapes have 3 dimensions—length, width, and depth. As a result of these dimensions these shapes have attributes of faces, edges and vertices.

An edge is a line where two faces of a three-dimensional shape meet. 

For example, a cube has 12 edges.

Vertices are corners where three faces meet. For example, a cuboid has 8 vertices.

Volume helps to find the space occupied by the given shape.
