Answered by GPT 3.5
To find the surface area of the aquarium, we need to find the area of each side and then add them all together.

1. Front and back sides: 17 inches long and 11 inches tall
Area = 17 inches x 11 inches = 187 square inches (2 sides)
Total area for front and back sides = 187 square inches x 2 = 374 square inches

2. Side walls: 9 inches wide and 11 inches tall
Area = 9 inches x 11 inches = 99 square inches (2 sides)
Total area for side walls = 99 square inches x 2 = 198 square inches

3. Top and bottom: 17 inches long and 9 inches wide
Area = 17 inches x 9 inches = 153 square inches (2 sides)
Total area for top and bottom = 153 square inches x 2 = 306 square inches

Total surface area = 374 square inches + 198 square inches + 306 square inches = 878 square inches

Therefore, Tommy and Cole need to buy 878 square inches of glass to enclose the aquarium.
