To find the surface area of a cube, you need to calculate the area of all six faces and then add them up.
Each face of the cube is a square with side length equal to the side length of the cube. Since the side length of the cube is 1.5m, the area of each face is 1.5m x 1.5m = 2.25 square meters.
Since a cube has 6 faces, the total surface area of the cube is 6 x 2.25 square meters = 13.5 square meters.
Therefore, the correct answer is:
c. 13.5 square meters
Each face of the cube is a square with side length equal to the side length of the cube. Since the side length of the cube is 1.5m, the area of each face is 1.5m x 1.5m = 2.25 square meters.
Since a cube has 6 faces, the total surface area of the cube is 6 x 2.25 square meters = 13.5 square meters.
Therefore, the correct answer is:
c. 13.5 square meters
