### Understanding Surface Area Calculation

#### Problem Statement:
Calculate the surface area of the rectangular prism depicted. The dimensions of the prism are provided as follows:
- Height: 12 inches
- Width: 14 inches
- Depth: 13 inches

#### Diagram Explanation:
The diagram showcases a three-dimensional rectangular prism. The edges of the prism are marked with the following measurements:
- One vertical edge is labeled as 12 inches.
- The width (horizontal base) is labeled as 14 inches.
- The depth (side base) is labeled as 13 inches.

#### Solution Options:
Students need to determine the surface area of this prism and round their answer to the nearest whole number. They can choose from the following options:
- 1012
- 2184
- 1540
- 2800

#### Calculation:
To find the surface area of a rectangular prism, you use the formula:
\[ \text{Surface Area} = 2lw + 2lh + 2wh \]
Where \( l \) is the length, \( w \) is the width, and \( h \) is the height.

Using the given dimensions:
- Length (l) = 13 inches
- Width (w) = 14 inches
- Height (h) = 12 inches

Plugging in these values:
\[ \text{Surface Area} = 2(13 \times 14) + 2(13 \times 12) + 2(14 \times 12) \]
\[ \text{Surface Area} = 2(182) + 2(156) + 2(168) \]
\[ \text{Surface Area} = 364 + 312 + 336 \]
\[ \text{Surface Area} = 1012 \]

Thus, the correct answer is 1012.

#### Answer Choices:
- 1012 ⬅️ (Correct Answer)
- 2184
- 1540
- 2800

By understanding and following the steps for calculating the surface area of a rectangular prism, students can solve this problem effectively.
