The figure is the net for a rectangular prism.
Dovator [93]
The surface area of the rectangular prism is 544 cm^2.

There are 3 pairs of different rectangles that form the rectangular prism.

If we find the area of each and add them up, we will have the surface area.

Here are the 3 pairs of rectangles:
6 x 16 = 96
8 x 16 = 128
6 x 8 = 48

2(96) + 2(128) + 2(48) = 544
