Surface area of a cubeTable of ContentSurface Area of CubeSummaryWhat’s Next?In the previous segment, we learnt how to find the surface area of a cuboid. In this segment, we will learn about the surface area of a cube.How to find the surface area of a cube?A cube is made up of square faces. Hence, its length, breadth, and height are equal. The surface area of a cube is the sum of the areas of its 6 square faces.CubeFor a cube with length, breadth and height as s units, the area of each face will be ?2square units.∴ Surface area of cube =6?2The lateral surface area of the cube includes the 4 squares at the side.
