Okay kiddo, so a snub dodecahedron is a 3D shape made up of 80 little flat surfaces called faces. Each face has five sides, and there are 12 big faces that are like pentagons.
Imagine you have a ball that's made of 12 pentagons joined together, kind of like a soccer ball. But instead of being all round like a ball, the snub dodecahedron has little corners sticking out between the pentagons.
It's kind of like taking a regular dodecahedron, which is a shape with 12 flat pentagon faces that are all the same size, and cutting off the corners a little bit.
The snub dodecahedron is a really cool shape because it's symmetrical, meaning it looks the same from different angles. Scientists and mathematicians like studying shapes like this to learn more about how the world works.
