To calculate the surface area of the triangular prism, we need to find the area of each face and add them together.
Face 1: 17.9 in x 18.4 in = 329.36 in²
Face 2: 17.9 in x 20.5 in = 367.95 in²
Face 3: 18.4 in x 20.5 in = 377.2 in²
Face 4 (Bottom): 18.4 in x 10.2 in = 187.68 in²
Face 5 (Back): 17.9 in x 10.2 in = 182.58 in²
Face 6 (Left side): 20.5 in x 10.2 in = 209.1 in²
Total surface area = 329.36 in² + 367.95 in² + 377.2 in² + 187.68 in² + 182.58 in² + 209.1 in² = 1653.87 in²
Rounded to the nearest whole number, the amount of wrapping paper needed is 1654 in².

I apologize for the mistake in my calculations. Let's find the correct surface area and amount of wrapping paper needed for the triangular prism.
The surface area of a triangular prism can be calculated using the formula:
Surface Area = 2*(base area) + (perimeter of base)*(height)
First, let's calculate the base area (triangle):
Base Area = 0.5 * base * height
Base Area = 0.5 * 17.9 in * 18.4 in
Base Area = 165.08 in²
Now, we need to calculate the perimeter of the base (triangle):
Perimeter = sum of all sides
Perimeter = 17.9 in + 20.5 in + 18.4 in
Perimeter = 56.8 in
Now, let's find the height of the triangular prism by using the last number, 10.2 in.
Surface Area = 2 * Base Area + Perimeter * Height
Surface Area = 2 * 165.08 in² + 56.8 in * 10.2 in
Surface Area = 330.16 in² + 579.36 in²
Surface Area = 909.52 in²
Rounding to the nearest whole number, the amount of wrapping paper needed to wrap the gadget is approximately 910 in². Thank you for bringing the error to my attention.
