Question

A student used a graduated cylinder to measure the volume of an irregularly-shaped rock. First, he added 25 mL of water to the graduated cylinder. Then, he placed the rock in the graduated cylinder. The graduated cylinder read 52 mL after adding the rock. What is the volume of the rock?
A.
52 mL
B.
77 mL
C.
25 mL
D.
27 mL

Answer 1

The volume of the rock is equal to the final volume of the graduated cylinder minus the initial volume of the water.
Therefore, the volume of the rock is 52 mL - 25 mL = 27 mL.

So, the correct answer is D. 27 mL.
