To find the amount of glass needed to enclose the aquarium, calculate the surface area of all six sides of the rectangular prism:
2(17 * 9) + 2(17 * 11) + 2(9 * 11)
= 2(153) + 2(187) + 2(99)
= 306 + 374 + 198
= 878 square inches
Therefore, Tommy and Cole would need to buy 878 square inches of glass to enclose the aquarium.
