Tommy and Cole are planning to build an aquarium for their pet fish . If the dimensions of the aquarium are 17 inches long and 9 inches wide and 11 inches tall how much glass do they need to buy to enclose the aquarium
To calculate the amount of glass needed to enclose the aquarium, we need to calculate the surface area of each of the four sides and the bottom of the aquarium.
The front and back sides have dimensions of 17 inches long and 11 inches tall, so the surface area of each side is 17 * 11 = 187 square inches. Since there are two of these sides, the total surface area for both front and back sides is 187 * 2 = 374 square inches.
The two side walls have dimensions of 9 inches wide and 11 inches tall, so the surface area of each side is 9 * 11 = 99 square inches. Since there are two of these sides, the total surface area for both side walls is 99 * 2 = 198 square inches.
The bottom of the aquarium has dimensions of 17 inches long and 9 inches wide, so the surface area of the bottom is 17 * 9 = 153 square inches.
Therefore, the total surface area of glass needed to enclose the aquarium is 374 (front and back) + 198 (side walls) + 153 (bottom) = 725 square inches.
Therefore, Tommy and Cole need to buy 725 square inches of glass to enclose the aquarium for their pet fish.
