Question

initial water volume - final water volume - use water displacement to determine the approximate volume of the solid object. a 21 ml. b 60 ml. c 24 ml. d 45 ml.

Explanation:

Step1: Identify initial volume

Initial water volume $V_1 = 21$ mL (from the first cylinder reading).

Step2: Identify final volume

Final water volume $V_2 = 45$ mL (from the second cylinder reading).

Step3: Calculate volume of solid

Volume of solid $V = V_2 - V_1=45 - 21 = 24$ mL.

Answer:

C. 24 mL
