Answer:
To calculate the amount of glass needed to enclose the aquarium, we need to find the surface area of the sides that will be covered.
The aquarium has six sides, but we don't need to enclose the bottom side. So, we will calculate the surface area of the other five sides.
The front and back sides have dimensions of 17 inches by 11 inches, so each side has an area of (17 inches) * (11 inches) = 187 square inches.
The two smaller sides (left and right) have dimensions of 9 inches by 11 inches, so each side has an area of (9 inches) * (11 inches) = 99 square inches.
The top side has dimensions of 17 inches by 9 inches, so it has an area of (17 inches) * (9 inches) = 153 square inches.
To find the total surface area, we add up the areas of these five sides:
Total surface area = (2 * 187 square inches) + (2 * 99 square inches) + 153 square inches
= 374 square inches + 198 square inches + 153 square inches
= 725 square inches
Therefore, you would need to buy at least 725 square inches of glass to enclose the aquarium.
