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
To calculate the amount of glass needed to enclose the aquarium, we need to find the surface area of the four sides and the bottom of the aquarium.
First, calculate the surface area of the front and back sides:
2 sides x (17 inches x 11 inches) = 374 square inches
Next, calculate the surface area of the two side walls:
2 sides x (11 inches x 9 inches) = 198 square inches
Then, calculate the surface area of the bottom:
17 inches x 9 inches = 153 square inches
Now, add up the surface areas of the four sides and the bottom:
374 square inches + 198 square inches + 153 square inches = 725 square inches
Therefore, Tommy and Cole will need to buy 725 square inches of glass to enclose the aquarium.
