A rock is dropped into a graduated cylinder containing 40 mL of water. The new volume is 47 mL. What is the volume of the rock?
A) 4 mL
B) 47 mL
C) 7 mL
D) 87 mL
E) 11 mL
I think it is 7 mL. Am I correct?
Answer (3)
To find the volume of irregularly shaped objects, you put them in graduated cylinders, as described. To find the volume of the object, get the difference between the original volume and the new volume. So, its 47mL - 40mL, which equals 7, so choice c) 7mL, the answer you picked!
The volume of the rock is 7mL . The correct option is** c)7ml**
From the question,
We are to determine the **volume **of the rock .
When an object is **submerged **in a container containing a liquid, the submerged object **displaces **a **volume **of liquid **equal **to the **volume **of the object .
That is,
Volume of object = Final volume - Initial volume
From the given information,
Initial volume = **40mL **
Final volume = **47mL **
∴ Volume of the rock = 47mL - 40mL
Volume of the rock = 7mL
Hence, the volume of the rock is 7mL . The correct option is** c)7ml**
