The walls, ceiling and floor of a cubic room need to be painted. The edge length for the cube is 3 m. What is the total surface area that will be painted in the room?
Since the shape is a cube, we know that all sides are the same length and therefore all faces and bases will have the same area. A cube will have a total of 6 faces/bases. The area of each one is 3 * 3 = 9 m^2 9m^2 * 6 = 54 m^2 The total surface area to be painted is 54m^2
