-- Surface area tells how much of a table a 2D shape will cover.
-- Volume tells how much water a 3D shape will hold.
-- It may be a bit confusing if you hear someone mention "the surface area of a cube".
What they're talking about is not really the surface area of the cube, but the surface
area of the faces of the cube ... the area of the construction paper or sheet metal that
you'd need in order to build the cube.
In the case of the cube ...
-- The area of one face is the 'square' (length x length) of the length of each edge.
-- The total area is 6 times the area of each face.
-- The volume is the 'cube' (length x length x length) of the length of each edge.
A small cell will have a larger surface-to-volume ratio.
To obtain the ratio of surface area to volume, divide the surface area by the volume.
surface area/ volume. wider range of surface area to volume is better for cells.
surface area divided by volume
Volume=area * length of that surface
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
You can't directly compare surface area and volume, since they use different types of units.

The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
You cannot compare volume and surface area and claim which one is bigger, because the units are different (units2 vs. units3) and it also depends on the type of unit used (e.g. inches, centimeters). You could compare volume and surface area numerically, but that would be virtually meaningless.I previously posted an example of a cube with side length 1 meter. In this cube, the volume is 1 m3 and the surface area is 6 m2, implying "larger" surface area. However, if we said that the side length was 100 centimeters (same value), the volume would be 106 cm3 and the surface area would be 6*104 m2. Here, the volume was "larger."
Volume does not, surface area does.

As volume increases surface area increase, but the higher the volume the less surface area in the ratio. For example. A cube 1mmx1mmx1mm has volume of 1mm3 surface area of 6mm2 which is a ration of 1:6 and a cube of 2mmx2mmx2mm has a volume of 8mm3 and surface area of 24mm2 which is a ratio of 1:3.
