Exploring Rational Expressions in Grade 6 Mathematics

This video tutorial by Matt covers the concepts of surface area and volume, explaining the differences between them and how they relate to three-dimensional shapes. It discusses various units of measurement for length, area, and volume, and provides practical examples such as measuring the perimeter of a parking lot and the volume of a semi-truck. The video includes an activity where students build shapes using cubes to explore surface area and volume. It also compares different prisms to highlight how surface area and volume can vary. The session concludes with a summary and homework instructions.

What does surface area measure?

• The covering on the outside of a 3D shape
