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)
surface area = square inches
First, we need to calculate the surface area of each side of the aquarium.
There are two sides that are 17 inches long and 11 inches tall, so their combined surface area is 2 * 17 * 11 = 374 square inches.
There are two sides that are 9 inches wide and 11 inches tall, so their combined surface area is 2 * 9 * 11 = 198 square inches.
There are two sides that are 17 inches long and 9 inches wide, so their combined surface area is 2 * 17 * 9 = 306 square inches.
Now, add up all the surface areas to get the total amount of glass needed:
374 + 198 + 306 = 878 square inches
Therefore, Tommy and Cole need to buy 878 square inches of glass to enclose the aquarium.
