Question

If the side length of the cube is 13 feet find the surface area

Answer 1

Answer:  1014 square feet

Work Shown:

$\text{SA} = \text{Surface area of the cube with side length x}\\\\\text{SA} = 6\text{x}^2\\\\\text{SA} = 6*13^2\\\\\text{SA} = 6*169\\\\\text{SA} = 1014$

Explanation:

The $\text{x}^2$ refers to the area of one square face with side length x. Each square face has an area of $\text{x}^2 = 13^2 = 169$ square feet. There are 6 identical faces to a cube, leading to a total surface area of 6*169 = 1014 square feet
