For intake measurement, where should the container be placed to measure volume accurately?

• A. In your hand
• B. On a tilting surface
• C. On a flat surface
• D. In the pocket

Answer: (C)

For accurate intake measurement, you want the container on a flat, stable surface so the liquid settles evenly and the reading isn’t shifted by angles or tilts. A flat surface prevents tilt that would make the level appear higher or lower than it truly is. Holding it in your hand or placing it on a tilting surface introduces angle error, and keeping the container in a pocket is unstable and unreadable. When you read the amount, look at the liquid’s level at eye level to avoid parallax error, but the essential placement is a flat surface.
