A 100 mL graduated cylinder was filled with water to the 50 mL mark. A rock was then added to the cylinder. After the rock was added, the volume of the cylinder

Question

Dont understand how to find volume

 

Answer 1

Some information is missing.  If we know how high the water level rose after adding the rock, we can subtract the initial mark (50 mL mark) from the final mark, and that gives the volume of the added rock.  I think that is what is missing from the problem statement:  To what level did the water rise after the rock was added?
