Tommy Cole are planning to build an aquarium for their pet fish. If the dimensions of the aquarium are 17 inches long 19 inches wide and 11 inches tall how much glass do they need to buy to enclose the aquarium
To find the amount of glass needed to enclose the aquarium, we need to calculate the surface area of each side of the aquarium.
The four sides of the aquarium (excluding the top and bottom) can be calculated as follows:
- 2 sides with dimensions 17 inches long and 11 inches tall: 2 * 17 * 11 = 374 square inches
- 2 sides with dimensions 19 inches wide and 11 inches tall: 2 * 19 * 11 = 418 square inches
The total surface area of the four sides is:
374 + 418 = 792 square inches
To enclose the top and bottom of the aquarium, we need to add:
- Top: 17 * 19 = 323 square inches
- Bottom: 17 * 19 = 323 square inches
The total surface area of all sides of the aquarium is:
792 + 323 + 323 = 1438 square inches
Therefore, Tommy Cole should buy 1438 square inches of glass to enclose the aquarium.
