Area of Prisms: The surface area of a cube

The video tutorial explains the concept of surface area for three-dimensional shapes, focusing on cubes. It begins with an introduction to 3D shapes and the specific properties of a cube, where all sides are equal. The tutorial derives the surface area formula for a cube, simplifying it from the general formula for a rectangular prism. The formula is shown to be 6L squared, where L is the length of a side. Practical applications are discussed, demonstrating how to use the formula to solve problems. The video concludes with tips on understanding and applying geometric formulas.

Why is the surface area of a cube simpler than that of a rectangular prism?

What does it mean when we say all sides of a cube are the same length?
