- B.The liquid has no surface tension.
- C.The liquid is at room temperature.
- D.The container is filled to the brim.
Model answer
What a good answer should say
- The container is perfectly cylindrical.
Explanation
Why this works
The correct answer is that the container is perfectly cylindrical. That assumption makes the volume estimate possible using a simple cylinder model.
The other options may affect real measurements, but they do not give the main shape assumption needed for this estimation problem.
