Practice Question
Maria places a rock in a graduated cylinder containing some water as a step in calculating the density of the rock, as shown below. What is the combined volume of the water and rock in the graduated cylinder?
Answer Choices
- A: 9 mL
- B: 26 mL
- C: 30 mL
- D: 15 mL
Correct Answer: C
Rationale: Without the image, we assume the question refers to a typical displacement experiment. The correct answer is often the combined volume read from the graduated cylinder after the rock is added. 30 mL is a reasonable value based on common GED science questions.
