Question

A rock is placed in a graduated cylinder to determine its volume. The following data are obtained. What is the volume of the rock?

Initial volume of water: 13.7 mL
Final volume of water: 28.9 mL

15.2 cm3
15.2 mL
15.2 cm
15.2 dm

Answer 1

Volume of rock= 28.9-13.7
= 15.2cm³ (cm³ is the unit of volume)

Answer 2

15.2 mL is the volume of the rock.

Step-by-step 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.
