To find the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6s^2 \]
where \( s \) is the length of a side of the cube.
In this case, the side length \( s \) is 1.5 meters.
Now, plug this value into the formula:
\[ \text{Surface Area} = 6(1.5)^2 \]
Calculating \( (1.5)^2 \):
\[ (1.5)^2 = 2.25 \]
Now multiply by 6:
\[ \text{Surface Area} = 6 \times 2.25 = 13.5 \text{ square meters} \]
Therefore, the surface area of the cube is 13.5 square meters.
