Final answer:
The volume of the aquarium is 56,313.25 cm³.
Step-by-step explanation:
The volume of an aquarium can be calculated by multiplying its length, width, and height. In this case, the length is 61 cm, the width is 30.5 cm, and the height is also 30.5 cm. To find the volume, we multiply these three dimensions together:
Volume = length × width × height
Volume = 61 cm × 30.5 cm × 30.5 cm = 56,313.25 cm³
