Work Shown:
[tex]\text{SA} = \text{Surface area of the cube with side length x}\\\\\text{SA} = 6\text{x}^2\\\\\text{SA} = 6*13^2\\\\\text{SA} = 6*169\\\\\text{SA} = 1014\\\\[/tex]
Explanation:
The [tex]\text{x}^2[/tex] refers to the area of one square face with side length x. Each square face has an area of [tex]\text{x}^2 = 13^2 = 169[/tex] square feet. There are 6 identical faces to a cube, leading to a total surface area of 6*169 = 1014 square feet
