Final answer:
The volume of the aquarium is calculated by multiplying its length, width, and height (3 ft x 2 ft x 2 ft), resulting in a volume of 12 cubic feet.
Step-by-step explanation:
To calculate the volume of the interior of an aquarium with the given interior dimensions, we use the formula for the volume of a rectangular prism: Volume = length × width × height. In this case, the dimensions provided are 3 feet by 2 feet by 2 feet. Plugging these dimensions into the formula gives us:
Volume = 3 ft × 2 ft × 2 ft = 6 ft² × 2 ft = 12 cubic feet.
Therefore, the volume of the interior of the aquarium is 12 cubic feet, which corresponds to choice G in the multiple-choice options presented.
