Explanation:
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.
