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)
To calculate the amount of glass needed to enclose the aquarium, we need to find the surface area of each of the six sides and add them together.
First, calculate the surface area of the bottom and top sides:
Bottom: 17 inches * 9 inches = 153 square inches
Top: 17 inches * 9 inches = 153 square inches
Next, calculate the surface area of the front and back sides:
Front: 17 inches * 11 inches = 187 square inches
Back: 17 inches * 11 inches = 187 square inches
Finally, calculate the surface area of the two side walls:
Side 1: 9 inches * 11 inches = 99 square inches
Side 2: 9 inches * 11 inches = 99 square inches
Add all the surface areas together:
153 (bottom) + 153 (top) + 187 (front) + 187 (back) + 99 (side 1) + 99 (side 2) = 878 square inches
Therefore, Tommy and Cole need to buy 878 square inches of glass to enclose the aquarium.
