Find da surface of a cube with sides measuring 11 meters

Question

A ) 726 m2

B ) 121 m2

C ) 132m2

D ) 66m2

Answer 1

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
