To find the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6 \times \text{side}^2 \]
In this case, the side length of the cube is 1.5 meters. First, calculate the area of one face:
\[ \text{Area of one face} = \text{side}^2 = (1.5 , \text{m})^2 = 2.25 , \text{m}^2 \]
Now, to find the total surface area:
\[ \text{Surface Area} = 6 \times 2.25 , \text{m}^2 = 13.5 , \text{m}^2 \]
Therefore, the surface area of the cube is 13.5 square meters.
