Geometry and Measurements: Lateral Area and the Total Area of a Cube

The video tutorial explains the properties of a cube, including its edges, vertices, and faces. It demonstrates how to calculate the total surface area of a cube by finding the area of one face and multiplying it by six. The concept of lateral area is introduced, which involves calculating the area of a cube without the top and bottom faces. An example is provided using a desk lamp. Finally, the video covers how to calculate the surface area of a cubic box without a lid, using the example of a gift box.
