What is the difference between 2D and 3D?

The major difference between 2D and 3D shapes is that 2-dimensional objects can only exist in a plane whereas a 3-dimensional object can be present in the three different planes at a time. The edges of the 2D object are clearly visible but not possible sometimes with a three-dimensional object.

As per the area and volume, what is the difference between 2D and 3D shapes?

As per the area and volume, the difference between 2D and 3D shapes is that 3D shapes can have both area and volume but a 2D shape can only have area but not volume. The volume of the 2-dimensional objects is considered 0.

What is the key difference between 2D and 3D objects based on the shape?

The key difference between 2D and 3D objects is that 2D objects can only have a planar shape which means they are only present on a single plane whereas 3D objects can have the shape in three different planes that is why the 3d objects are not called planar objects.

A 2D object is an object which exists only in 2 possible dimensions. They have length and height but not width. The 2-dimensional object will not have volume as well, this is the major reason why a 2-dimensional object differs from a 3-dimensional object.

A 3D shape is a shape that exists in 3 different dimensions. They have all three dimensions which are length, width and height. They can occupy space and have volume. The common examples of 3D objects are tables, chairs, bottles, pens, copies, etc.

We are surrounded by objects of various shapes and sizes. The existence of the objects can be in various dimensions(D). Some objects exist in 1D, some in 2D while major objects exist in 3D. The main difference between 2D and 3D shapes is that 2D shapes have or exist in only two dimensions, whereas 3D shapes have or exist in 3 Dimensions.

The difference between 2D and 3D is that the mathematical axes used in 2D are x and y-axes, and the mathematical axes used in 3D are x, y, and z axes. Here, we will first discuss the difference between 2D and 3D shapes based on various factors such as axes, view, edges, and a lot more thereafter we will see what is the 2D shape and what is a 3D shape in brief.

Difference Between 2D and 3D Shapes

The difference between 2D and 3D shapes is that all of the edges of 2D shapes are plainly observable. On the other hand, some of the edges in 3D shapes are hidden. There exists various differences between these two shapes which are elaborated in the table provided below.

Key Differences Between 2D and 3D

2D Shapes	3D Shapes
2D Refers to a 2-dimensional object.	3D Refers to a 3-dimensional object.
Only two dimensions of the object exist.	3 dimensions of the objects exist.
They can be present in the x-y axis or x-z axis or y-z axis at once and can not be present in all three at the same instance.	They exist on the x, y, and z-axis.
They only occupy the area.	They occupy area and volume, both.
All the edges of the object lie in the same plane.	Edges of the object can exist in different planes.
They only have length and height.	They have length, width and height.
Examples: triangle. square, circle, rhombus, etc.	Examples: Rohmboid, cuboid, pyramid, octahedron, dodecahedron, etc.

What are 2D Shapes?

2D shapes are also known as 2-dimensional shapes where D stands for dimension. They have both height and length. They only exist in a single plane hence called plane figures or plane objects. They can have area but not volume.

The 2D object can not exist in the third plane, for example, if a square exists in the x-y plane then it won't be present on the z-axis. All the corners or edges of the 2D objects are visible. The most common examples of 2D objects are paper sheets, squares, rectangles, triangles, circles, etc.

What are 3D Shapes?

3D or 3-dimensional objects are objects which exist in 3 dimensions. They will have length, width, and breadth. The existence of the 3D object can be in 3 different planes at once. The 3-dimensional objects can have area as well as volume.

We can see 3-dimensional objects anywhere we are. There are various 3D objects around us such as trees, tables, chairs, bottles, laptops, cameras, glass, etc.
