Okay kiddo, have you ever played with a toy that was really flat, like a piece of paper, but then when you folded it in certain ways it turned into something that looked 3D or like it had depth? Well, that's kind of what a 3D figure is!
Imagine a regular drawing, you can only see the outline of the shape, right? But with a 3D figure, it looks like it has a front, back, sides, top and bottom! How cool is that?
Now, think about a real toy, like a ball. You can see all around the ball, right? And it doesn't just have a front, or a back, but it curves around and looks different depending on where you're looking at it from. That's what a 3D figure can do too!
You can make 3D figures on a computer or with special materials like clay or even paper! And when you look at it, you can see all around it, just like a real toy. It helps make things look more realistic and fun to play with.
So, if you ever come across a 3D figure, try to look at it from all angles and see how it looks different. It's like having your own mini toy that you can see from all sides!
