The surface area \( A \) of a cube can be calculated using the formula:
\[ A = 6s^2 \]
where \( s \) is the length of one side of the cube.
In this case, the side length \( s \) is 11 meters:
\[ A = 6 \times (11)^2 \] \[ A = 6 \times 121 \] \[ A = 726 , \text{m}^2 \]
So, the surface area of the cube is \( 726 , \text{m}^2 \).
The correct answer is:
A) 726 m²
