Answer

\text{16 square units}

4 steps

To calculate the surface area of the rectangular prism shown in the image, we use the formula:

SA = 2lw + 2lh + 2wh

where $l$ is the length, $w$ is the width, and $h$ is the height.

Identify the dimensions from the image.
From the image, we can determine the dimensions:
- Length ( $l$ ) = 2 units
- Width ( $w$ ) = 1 unit
- Height ( $h$ ) = 2 units
Substitute these values into the surface area formula.
$SA = 2(2)(1) + 2(2)(2) + 2(1)(2)$
Calculate each term.
$SA = 2(2) + 2(4) + 2(2)$ $SA = 4 + 8 + 4$
Add the terms to find the total surface area.
$SA = 16 \text{ square units}$
The surface area of the rectangular prism is $\text{16 square units}$ .
