Answer:
127.8 in²
Step-by-step explanation:
To find surface area you must add the area of each face (6 faces on a rectangular prism).
There will be 2 faces that are:
3.7 x 6
3.7 x 4.3
6 x 4.3
The area of these would be 22.2, 15.91, and 25.8 (in that order).
We multiply each by 2 sense the opposite side of each face are the same.
22.2 × 2 = 44.4
15.91 ×2 = 31.82
25.8 × 2 = 51.6
Now the sum of each of these will be the surface area of the prism.
44.4+31.82+51.6=127.82
Rounded to the nearest tenth is 127.8
