To calculate the amount of glass needed to enclose the aquarium, we need to find the surface area of all six sides.
The aquarium has 2 sides that are 17x11 (length x height) = 187 square inches each.
It also has 2 sides that are 9x11 (width x height) = 99 square inches each.
And 2 sides that are 17x9 (length x width) = 153 square inches each.
Adding all 6 sides together gives:
2(187) + 2(99) + 2(153) = 374 + 198 + 306 = 878 square inches
Therefore, Tommy and Cole will 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?
