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.
