Polyhedral surface

Polyhedral surface is like playing with building blocks to create a shape. Imagine you have many square blocks with different colors and you stack them up to make a square-shaped tower. That tower is like a polyhedral surface.

The blocks you used to make the tower represent the different faces of the polyhedral surface. Each face is a flat surface that is connected to other faces at the edges, just like the blocks in your tower.

The tower itself is a 3D shape, and the same goes for a polyhedral surface. It has height, width, and depth, and it is made up of many faces that are connected together.

Just like with your tower, you can make polyhedral surfaces with different shapes and sizes by using different types of building blocks or faces. Some polyhedral surfaces are made up of triangles, others are made of squares or other shapes.

Overall, a polyhedral surface is a 3D shape made up of many flat faces that are connected together at their edges, just like building blocks.
