Find the surface area of the prism. write your answer as fraction or mixed number.

From the measure the picture provides us, we can conclude that the prism is a cube, which also tells us that all 6 sides of this prism have equal surface area, so we only need to calculate one of them and multiply the result by 6:

The surface area of one side of the cube should be: 2/3 . 2/3 = 4/9 (ft²)

The surface area of the prism should be: 4/9 . 6 = 24/9 = 8/3 (ft²)

the correct is answer is a 9-sided polygon!
