Brawn is better than brain

I think Brawn is better than brains because you can do lots of stuff like soccer, rugby, and boxing.
in writing, we have been doing persuasive writing.

In math, we have been doing slides on shapes and their dimensions e.g.  2d and 3d.
We had to include how many faces how many vertices and how many edges.

What is the difference between a 2D & 3D shape? Please tell me in the comments below!
