Perimeter, Area, and Volume

What are the three dimensions when you watch a 3-D movie? Have you ever thought about it? We say a movie is 3-D when it seems to have length, width, and depth. It is almost as if you could touch the scenes.
In class, we've read the book Perimeter, Area, and Volume - A Monster Book of Dimensions by David A. Adler and discussed some dimensions.

Each one of us has three dimensions, we are not flat.

We also discussed the use of measurement units when we talk about perimeter and area. We saw that when we measure the perimeter, we use metric or US standard units like: cm, m, km, in, ft, yd... And, when we measure area we use square units of measurement like: cm², ft², m², in²...

Hope you've enjoyed our measurement classes. We'll start a new topic soon.

See you ;) Ms. Sarah Giansante
