Explanation: The surface area of a cube can be found by adding up the areas of all six faces. Since all the faces of a cube are congruent squares, the formula for the surface area of a cube is 6s^2, where s is the length of one side. In this case, s=1.5 meters, so the surface area would be 6 * (1.5)^2 = 13.5 square meters.
