Surface Area and Volume of Prisms

This video tutorial for sixth graders covers Big Ideas Math Section 8.2, focusing on the surface areas of prisms. The lesson begins with an introduction and objectives, followed by two examples: finding the surface area of a rectangular prism and a triangular prism using nets. The tutorial concludes with assignment instructions and reminders for the next class.

What is the main objective of today's lesson?

• To understand the properties of triangles

• To calculate the perimeter of a rectangle

• To use a net to find the surface area of a prism
