Question

To calculate the volume of an irregular object we need to:

• A. add initial volume and final volume
• B. subtract final volume from initial volume
• C. subtract the initial volume from the final volume
• D. none of these

Answer 1

The correct option is C

subtract the initial volume from the final volume

The explanation for correct option:

Option (C): subtract the initial volume from the final volume

1. For finding the volume of the irregular-shaped body we use a measuring cylinder.
2. Measuring cylinder is an instrument using which we can calculate volume by the change in volume of the water in the cylinder.
3. So when the object is dropped in the cylinder so the volume of water increases.
4. So we can calculate the volume of the body by subtracting the subtract the initial volume of the cylinder from the final volume of the cylinder.
5. $V_2$ is final the volume and $V_1$ is the initial volume.

Hence, the correct answer is an option (C).
