Question

When Josiah opens and lays a cereal box out flat, he sees that the top and the bottom of the box both measure 2 inches by 8 inches, the sides of the box both measure 2 inches by 11 inches, and the front and back of the box both measure 8 inches by 11 inches. What is the surface area of Josiah's cereal box?

Answer 1

252 square inches is the surface area of Josiah's cereal box.

Explanation:

1. Let's review the information given to us to answer the question correctly:

Height of the box = 11 inches

Length of the box = 8 inches

Width of the box = 2 inches

2. What is the surface area of Josiah's cereal box?

Let's recall the surface area of a rectangular prism:

Surface area = 2 (width * length + height * width + length * height)

Surface area = 2 (2 * 8 + 11 * 2 + 8 * 11)

Surface area = 2 (16 + 22 + 88)

Surface area = 2 * 126

Surface area = 252 inches²
