Calculate the surface area of the composite figure shown.

2 rectangular prisms. One prism has a length of 8, width of 8, and height of 2. The second prism has a length of 8, width of 2, and height of 4.

Back Prism:

1 base: 8 by 8

4 lateral faces: 8 by 2

One shared base: 64 – 32 = 32 square units

Front Prism:

1 base: 8 by 4

2 lateral faces: 8 by 2

2 lateral faces: 2 by 4

One shared base: area covered by other prism

Total surface area:
