To find the amount of glass needed to enclose the aquarium, we need to find the surface area of all the sides.
Surface area of the front and back sides (17 inches long by 11 inches tall):
2 * (17 inches * 11 inches) = 374 square inches
Surface area of the left and right sides (9 inches wide by 11 inches tall):
2 * (9 inches * 11 inches) = 198 square inches
Surface area of the top and bottom sides (17 inches long by 9 inches wide):
2 * (17 inches * 9 inches) = 306 square inches
Total surface area:
374 + 198 + 306 = 878 square inches
Therefore, Tommy and Cole need to buy 878 square inches of glass to enclose the aquarium.
Tommy and Cole are planning to build an aquarium for their pet fish. If the dimensions of the aquarium are 17 inches long, 9 inches wide, and 11 inches tall, how much glass do they need to buy to enclose the aquarium? (1 point)
