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:
