# What is the surface area to volume ratio for a cube that measures 4 cm on each side?

You calculate the total surface area by finding the area of a single side of the cube and then multiplying that area by six (for the six sides of a cube).

Once you do this you will find that a 4cm Cube has a total surface area of

To find the volume you simply use the following formula:

In this case (because it is a cube) you will use 4cm for each value:

To find the ratio of surface area to volume, simply divide the surface area by the volume:

Ratio

Ratios are generally unit-less as they are comparing two values rather than combining to form a new value.
