Understanding the Surface Area of a Cube

This lesson explains how to calculate the surface area of a cube. It begins by introducing the formula for the surface area, which is 6x squared, where x is the side length of the cube. The lesson then details how to calculate the area of one face of the cube, which is x squared, and extends this to find the total surface area by multiplying by six. An example is provided where the side length is 8 centimeters, resulting in a surface area of 384 square centimeters. The lesson concludes by reiterating the formula and its application.
