# Solid Geometry

Solid geometry deals with 3 dimensional shapes in 3 dimensional space.

You will be introduced to all 3d shapes names and pictures.

This tutorial will teach how a 3d shape is formed from the origin step by step.

You will have learned 3d shapes properties.

Solid geometry deals with 3 dimensional shapes and figures in 3 dimensional space.

It is the traditional name of 3 dimensional geometry in Euclidean space.

A solid has length, width and height or depth. So, a solid is of 3 dimensions.

Solid geometry includes all 3d shapes names and pictures.

Pay a close attention! Stereometry is a branch of geometry, correlated to solid geometry. It deals with the measurement of volume of solid figures.

Therefore, solid geometry mainly discusses the measurements of volume of solid shapes and 3d shapes properties.

Cubiod, cube, cone, cylinder, prism, pyramid, for example, all are 3 dimensional figures can be formed in 3 dimensional space.

## A Prism

We see a prism.

Are you interested in playing with 3d shapes names and pictures or love to finding out 3d shapes properties?

At first, you need to have a clear concept of geometric dimensions.

If you want, study geometric dimensions.

### How a Solid Shape Formed

You can see a green colored fixed point in the first figure. A point is just a position. It has no length or width.

In the second figure, a set of continuous points adds up to a line. It has only length (breadthless length). And adding more continuous points makes the line longer.

In the third figure, arranging a set of lines one after another makes a plane. Adding up more lines extends the plane infinitely far. A plane has lenght and width. Thus a plane is of two dimension.

And lastly, six planes obtained from the third figure make a cuboid or solid. Cuboid is one of the 3d shapes names and pictures. It has length, width and height. So a solid is 3 dimensional figure.

A list of 3d shapes names are shown below.

• Polyhedron
• Cuboid
• Cube
• Cylinder
• Cone
• Sphere
• Prism
• Pyramid

### Polyhedron

Polyhedron is a solid shape in elementary geometry. A polyhedron must have flat polygonal faces. Its edges are straight. And its vertices or corners are sharp.

Thus a solid is said to be polyhedron consists of flat polygonal faces, straight edges and sharp vertices.

So, a polyhedron is also one of the 3d shapes names and pictures in 3 dimensional space.

Two different polyhedrons (also polyhedra) are shown in the figures above.

All faces of both figures are flat polygonal.

Each joining edge is straight line (not curve).

All vertices or corners of each figure are sharp.

The two figures above are polyhedrons as they satisfy all the conditions of a polyhedron.

A list of 3d shapes names and pictures with 3d shapes properties are given below.
