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
