Answer:
15.2 mL is the volume of the rock.
Explanation:
Initial volume of the water in graduated cylinder= 13.7 mL
Final volume of the water in graduated cylinder= 28.9 mL
Volume occupied by the rock = x
V + x = V'
Where, V = Inital volume of water
V'= Final volume of the water
x = 28.9 mL - 13.7 mL =15.2 mL
15.2 mL is the volume of the rock.
