Q:
I am in first grade. We are studying dimensions like 3 dimensional objects. I want to know what dimension is air. I know that air is tiny tiny stuff that you can't see that joins together but looks like it is all one thing. So I was just wondering if air has a dimension. Thanks.

A:
If you think of the air in a room, it stretches out in all the directions, up-down, front-back, left-right. So it fills a three-dimensional space.

If you're wondering about each molecule of the air, it's true that it is very small. However, its outer part is a fuzzy electron cloud that has three dimensions, just like a cloud you would see in the sky.
