Surface area of a cube

Learning Objectives Define the surface area of a cube and identify its key properties. Derive and explain the formula for the total surface area of a cube. Calculate the total surface area of a cube given its side length. Calculate the side length of a cube given its total surface area by using algebraic manipulation and radical expressions. Differentiate between total surface area and lateral surface area. Apply the surface area formula to solve real-world problems.

TermDefinitionExample CubeA three-dimensional solid object with six identical square faces, twelve equal edges, and eight vertices.A standard six-sided die is a perfect example of a cube. FaceOne of the flat, square surfaces of a cube. A cube has 6 identical faces.The side of a die showing the number '4' is one of its faces. EdgeA line segment where two faces of a cube meet. A cube has 12 equal edges.The line where the top of a box meets the side of the box. Side Length (s)The length of any one of the cube's 12 edges. Since all faces are squares, the length and width of each face are equal to the side length.If a sugar cube measures 1 cm from one corner to the next along a straight line, its side length (s) is 1 cm. Surface Area (SA)The total area of the outer surface of a...

Area of a Single Face A = s^2 Since each face of a cube is a square, its area is the side length multiplied by itself. Use this to find the area of one of the six faces. Total Surface Area (TSA) SA = 6s^2 This is the primary formula for a cube's surface area. It represents the area of one face (s²) multiplied by the total number of faces (6). Lateral Surface Area (LSA) LSA = 4s^2 This formula calculates the area of the 'sides' of the cube only, excluding the top and bottom faces. It is the area of one face (s²) multiplied by four.
