Okay kiddo, let's talk about polyhedrons!
Polyhedrons are basically objects that have flat surfaces, like a cube or a pyramid. Think of them like a big ball made out of flat shapes stuck together.
Imagine you have a bunch of square cards and you stick them together by their edges. You can make a cube out of it. A cube is a type of polyhedron.
Now, there are different types of polyhedrons depending on the number and shape of their faces.
For example, a pyramid is a type of polyhedron that has one flat surface (called a base) and all the other surfaces slant up from the corners of the base to meet at a point on top.
There are also polyhedrons that have more complex shapes and angles, like a dodecahedron which has 12 flat, pentagon-shaped faces.
Polyhedrons can come in all shapes and sizes, and they're super cool to look at and play with. Pretty neat, huh?
