Volume Ratio Calculator

Enter the total surface area of an object and the total volume into the calculator to determine the surface to volume ratio.

Volume Ratio Formula

The following formula is used to calculate a surface area to volume ratio.

VR = SA / V

  • Where VR is the volume ratio
  • SA is the total surface area
  • V is the total volume

It’s important that the units for surface area and volume are consistent. For example, if the surface area is measure in ft^2, then the volume must be measured in ft^3.

Volume Ratio Definition

A volume ratio is defined as the ratio of the total surface area to the total volume of an object or shape.

Volume Ratio Example

How to calculate a volume ratio of a cube?

  1. First, determine the length of the side.

    For this example, we will say this is 2 for this example.

  2. Next, determine the surface area.

    The surface area of a cube with side 2 is 6*2^2 = 24.

  3. Next, determine the volume.

    Using the formula V = a ^3 we find the volume to be 2^3= 8.

  4. Finally, calculate the volume ratio.

    Using the formula above, we find the volume ratio to be 24/8 = 3.
