### What are 3D Shapes?

A 3D shape is also called a 3-dimensional shape with specific properties, including the number of edges, faces, and vertices. All 3D shaped objects are solids having some measurements in the X, Y, and Z-axis called length, breadth, and height, which are also called the dimensions of the solid object.

3D shapes are usually arisen by the rotation of the 2D shapes.

### Some properties of 3D shapes:

3D shapes or solids have some properties according to their shapes and sizes,

**Vertices:**A vertex is a corner point where the edges meet.**Edges:**An edge is simply a line segment drawn between the faces.**Faces:**A face is a curve or flat surface on the 3D surface covered by its edges.

### Description of 3D Shapes:

**Cube:**

A cube is defined as a three-dimensional square with six equal sides. All the faces of the cube have equal dimensions. All angles are equal and right-angled triangles.

**2. Cuboid:**

A cuboid is also known as a rectangular prism. The faces of the cuboid are rectangular. It has six faces, eight edges, and eight vertices, respectively.

**3. Cone: **A cone is a solid object that has a circular base and has a single vertex. It is a geometrical shape that tapers.

**4. Cylinder:**

A cylinder is a solid geometrical figure that has two parallel circular bases connected by a curved surface. It doesn’t have any vertices.

**5. Prism: **

A prism always contains the same shape or face on either side.

**6. Pyramid: **

A pyramid with all upper faces is isosceles triangles that connect at a single vertex, and the base surface is like a square.

**7. Hemisphere (half sphere)**:

A hemisphere looks like a cut portion of the sphere. The cut surface looks like a circle, and the other portion is like a solid semicircle.

**8. Tetrahedron (Triangular pyramid)**:

A pyramid with all faces like a triangle is called a tetrahedron. It has six edges, four faces, and four vertices, respectively.

**9. Square pyramid (Square based pyramid): **

A square pyramid is a pyramid that has a square base, and the rest faces are like triangles together connected at a single vertice at the tip.

**10. Sphere:**

A sphere is a Rounded Solid ball that does not contain any flat surface and edges and vertices

**11. Polyhedron:**

A polyhedron is a solid and 3D shape that contains flat surfaces and straight edges. A regular polyhedron is a 3D shape having all faces are of the same shape.

**12. Dodecahedron:**

A dodecagon is also called a regular polyhedron whose all faces are of the same shape. It has 12 faces, and all are like pentagons.

**13. Triangular prism:**

Triangular Prism is a prism having two triangular faces whose vertices are connected by an edge forming a rectangular face. It has six vertices, nine edges, and five faces.

**14. Torus:**

A torus is a donut-shaped solid having a hole in between and forms a ring-like structure.

**15. Pentagonal prism:**

Pentagonal prism is a prism having two pentagonal faces connected with their vertices.
