C. 18 square meters
The surface area of a cube is calculated by finding the area of each face and then adding them all together. Since all faces of a cube are identical, we can find the area of one face and then multiply by 6 to get the total surface area.
Each face of the cube with a base of 1.5 meters has an area of 1.5 * 1.5 = 2.25 square meters. Multiplying that by 6 gives us a total surface area of 2.25 * 6 = 13.5 square meters.
