Final answer:
The length of one side of the aquarium is 1.5 feet.
Step-by-step explanation:
To find the length of one side of the aquarium, we can solve the equation s^3 = 3.375. Taking the cube root of both sides, we get s = ∛3.375. Evaluating this expression, we find that the length of one side of the aquarium is approximately 1.5 feet. Therefore, the correct answer is A. 1.5 feet.
