Braden chose C as the answer. Why is his answer incorrect?

Answer 1

Braden is incorrect because the correct answer is B. He included the top face of the box

Explanation:

To find surface area, just add up the areas of all of the sides of the shape. In this case, you would have one side with 144 in^2 (12 * 12) and four sides with 120 in^2 (10 * 12). Add these together and you get 624
