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.
Given that the side length \( s \) is 11 meters, we can calculate:
\[ \text{Surface Area} = 6 \times (11 , \text{m})^2 = 6 \times 121 , \text{m}^2 = 726 , \text{m}^2 \]
Therefore, the surface area of the cube is 726 m².
The correct response is: 726 m²
