Answer:
The total surface area is 140.4
Step-by-step explanation:
If we start with the larger surfaces on the top and bottom, we can find both of their surfaces by multiplying 4 by 6.5.
4*6.5=26. Since there are 2 of these surfaces, we can multiply 26 by 2 to get 52.
Then, we can find the surface area of the sides by multiplying 6.5 by 3.4.
6.5*3.4=22.1 Since there are four of these surfaces, we can multiply 22.1 by 4 to get 88.4.
Now, all we have to do is add them together.
52+88.4=140.4
The total surface area is 140.4
Hope this helps! :D
