Which method is most appropriate for measuring the volume of an oddly-shaped, non-geometric solid object?

• A. Calculate volume using length × width × height
• B. Estimate volume by weighing the object
• C. Use water displacement in a graduated cylinder
• D. Measure volume using a ruler and protractor

Answer: (C)

Verified step by step guidance

1. Understand that for regular geometric solids, volume can be calculated using formulas like length × width × height, but this method is not suitable for oddly-shaped objects.
2. Recognize that estimating volume by weighing the object requires knowledge of the object's density, which may not be readily available or accurate for irregular shapes.
3. Recall that water displacement is a practical method to measure the volume of irregularly shaped solids by submerging the object in water and measuring the change in water level.
4. Use a graduated cylinder filled with a known volume of water, then carefully submerge the object completely without spilling water, and record the new water level.
5. Calculate the volume of the object by subtracting the initial water volume from the final water volume; this difference equals the volume of the irregular solid.
