The video tutorial explains how to calculate the lateral and total surface areas of a cube. It begins by defining a cube as a type of rectangular prism and explains that the lateral surface area is the sum of the areas of the four side faces, which are squares. Therefore, the lateral surface area is four times the area of one square face. The total surface area is the sum of the lateral surface area and the areas of the top and bottom faces. Since a cube has six equal square faces, the total surface area is six times the area of one face.
