Answer 2

Solution

The surface area of the cube will be the sum of the area of the bases and the area of vertical surfaces of the cube. Since all the faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added five times to itself. It is measured as the "number of square units" (square centimeters, square inches, square feet, etc.). The surface area of a cube can be of two types,

Lateral surface area

The lateral surface area of a cube refers to the total area covered by the side or lateral faces of a cube.

Total surface area
