The surface area of a cube can be found by calculating the area of each of the six square faces and then adding them together. Since all the sides of a cube are equal, the area of each face is the same.
Given that the height of the cube is 1.5 meters, the area of one face would be (1.5 m) x (1.5 m) = 2.25 square meters.
Therefore, the total surface area of the cube would be 2.25 square meters x 6 faces = 13.5 square meters.
So, the correct answer is:
• 13.5 square meters.
