Cube Geometry Concepts

This video tutorial covers Lesson 18, focusing on the surface area and volume of cubes. It begins with a cube having an edge length of 5 inches, explaining how to draw a net and calculate its surface area and volume. The lesson progresses to a cube with a 17-unit edge length, demonstrating similar calculations. Finally, the tutorial introduces using a variable 's' to represent edge length, providing expressions for surface area and volume applicable to any cube.
