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 long wide and 11 inches tall how nmuch glass do they need to buy to enclose the aquarium
To calculate the amount of glass needed to enclose the aquarium, first find the surface area of each side of the aquarium.
The aquarium has:
- 2 sides that are 17 inches long and 11 inches tall (17 * 11 = 187 square inches each)
- 2 sides that are 9 inches long and 11 inches tall (9 * 11 = 99 square inches each)
- 1 bottom that is 17 inches long and 9 inches wide (17 * 9 = 153 square inches)
- 1 top that is the same as the bottom (153 square inches)
Now, add up the surface areas of each side:
(2 * 187) + (2 * 99) + 153 + 153 = 374 + 198 + 153 + 153 = 878 square inches
Therefore, Tommy and Cole need to buy 878 square inches of glass to enclose the aquarium.
