Use the image to answer the question.
There are four adjoining rectangles of the same height positioned so their vertical sides touch. The first and third rectangles from the left are the same size as each other. The second and fourth rectangles from the left are also the same size as each other but wider than the first and third. The first rectangle is labeled 7 centimeters on the left side and 2 centimeters on the bottom side. The fourth rectangle is labeled 10 centimeters on the bottom side. The second rectangle has identical small rectangles touching its top and bottom sides. The small rectangles are the same width as the second rectangle.

The surface area of a rectangular prism is calculated as follows:
Surface Area = 2lw + 2lh + 2wh
Given the dimensions from the image:
l = 7 cm (length), w = 2 cm (width), h = 10 cm (height)
Plugging in the values:
Surface Area = 2(7*10) + 2(7*2) + 2(2*10)
Surface Area = 140 + 28 + 40
Surface Area = 208 cm^2
Therefore, the correct answer is:
208 cm^2
