The surface area of a cube can be calculated by adding up the areas of all six faces. Since all faces of a cube are squares and have equal area, we can calculate the surface area by finding the area of one face and then multiplying by 6.
The area of one face of the cube can be calculated as:
Area = side^2
Area = (1.5 meters)^2
Area = 2.25 square meters
Since there are 6 faces on a cube, the total surface area of the cube is:
Surface Area = 6 * Area of one face
Surface Area = 6 * 2.25 square meters
Surface Area = 13.5 square meters
Therefore, the surface area of the cube is 13.5 square meters.
