**What’s after a dodecahedron?**

Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron.

**What are the faces of most 3D shapes?**

The faces of most of the 3D shapes are polygons like a triangle, square, rectangle. What can a 3D Shape also be Called? In geometry, a three-dimensional shape can also be called a solid shape.

## What are 3D shapes with regular polyhedrons called?

Next, let’s learn about 3-dimensional shapes with regular polyhedrons (platonic solids). A polyhedron is a 3D shape that has polygonal faces like (triangle, square, hexagon) with straight edges and vertices. It is also called a platonic solid. There are five regular polyhedrons.

**What is a three-dimensional shape?**

Three-dimensional shapes, by their nature, have an inside and an outside, separated by a surface. All physical items, things you can touch, are three-dimensional. This page covers both straight-sided solids called polyhedrons, which are based on polygons, and solids with curves, such as globes, cylinders and cones.

**What are the examples of 2D and 3D shapes?**

Examples of 2D shapes are triangle, square, rectangle, and examples of 3D shapes are cube, cuboid, prism. What are the Surface Area and Volume of a 3D Shape?
