Answer:
Volume of the rock, V = 2 mL
Step-by-step explanation:
It is given that,
Water filled in a graduated cylinder is 3 mL
She then drops a small rock into the cylinder and the water level rises to the 5 mL mark
We need to find the volume of the rock.
The volume of the rock is equal to the difference in volume mark. So,
V = 5 mL - 3 mL
V = 2 mL.
