Volume Decrease Formula

The following formula is used to calculate the final volume after a decrease:

FV = IV * (1 - DR / 100)

Variables:

  • FV is the final volume after the decrease (cubic units)
  • IV is the initial volume (cubic units)
  • DR is the decrease rate (percentage)

To calculate the final volume after a decrease, multiply the initial volume by one minus the decrease rate divided by 100.

What is Volume Decrease?

Volume decrease refers to the reduction in the space that an object or substance occupies, often as a result of external factors such as pressure, temperature change, or chemical reactions. Understanding volume decrease is important in fields such as chemistry, physics, and engineering, where it is essential to predict how materials will behave under different conditions.

How to Calculate Volume Decrease?

The following steps outline how to calculate the final volume after a decrease:

  1. First, determine the initial volume (IV) in cubic units.
  2. Next, determine the decrease rate (DR) as a percentage.
  3. Use the formula FV = IV * (1 – DR / 100) to calculate the final volume (FV).
  4. Finally, enter the values into the calculator to verify the final volume after the decrease.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Initial Volume (IV) = 500 cubic units

Decrease Rate (DR) = 20%
