Calculating Surface Area Concepts

This video tutorial covers lesson 23 from the workbook, focusing on calculating the surface area of various geometric shapes. It begins with an introduction to the lesson and a review of surface area concepts. The tutorial then delves into calculating the surface area of a square pyramid, followed by a rectangular prism with unequal sides. The video also explores more complex shapes, providing step-by-step instructions and exercises for students to practice. The tutorial emphasizes understanding the relationships between different shapes and their surface areas.
