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 two enclosed the aquarium

To find the surface area of the aquarium, we need to find the area of each of the six sides and add them together.

The two sides that are 17 inches long and 11 inches tall each have an area of 17 * 11 = 187 square inches.

The two sides that are 17 inches long and 9 inches tall each have an area of 17 * 9 = 153 square inches.

The two sides that are 9 inches wide and 11 inches tall each have an area of 9 * 11 = 99 square inches.

The total surface area is therefore 2(187) + 2(153) + 2(99) = 374 + 306 + 198 = 878 square inches.

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