Calculating Area and Prisms

This lesson covers the concept of prisms, their types, and how to calculate their surface area. It explains the properties of different prisms, such as triangular, square, and hexagonal prisms, and provides a detailed example of calculating the surface area of a square prism. The lesson also includes a practical application of calculating the cost of canvas for a tent and converting square feet to square yards. The session concludes with a brief introduction to the next lesson on using fractional edge lengths for volume.
