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?

Surface area = ( ) square inches

Surface area = 2(Length x Width) + 2(Length x Height) + 2(Width x Height)

Surface area = 2(17 x 9) + 2(17 x 11) + 2(9 x 11)
Surface area = 2(153) + 2(187) + 2(99)
Surface area = 306 + 374 + 198
Surface area = 878 square inches

Therefore, Tommy and Cole would need to buy 878 square inches of glass to enclose the aquarium.
