Surface area and volume calculated separately. Then the ratio is taken
The rate at which the cell increases in size depends on the DNA. The ratio of the surface area (calculated: length x width x # of sides) is divided by the cell volume (calculated: length x width x height). THE VOLUME OF THE CELL INCREASES MORE RAPIDLY THAN THE SURFACE AREA, CAUSING THE RATIO OF SURFACE AREA OVER VOLUME TO DECREASE. This decrease causes cell malfunction. If the cell volume increases too much, then the ratio will decrease causing problems for the cell's regular functions.

Lets say the cell is cuboidal. The surface area of a 1 inch cube is (1X1) 6 or 6 square inches. The volume of the cell is HXWXH or 1X1X1 or 1 cubic inch. The ratio of surface area to volume is 6:1.
Cell indices are usually calculated from tests performed on an automated electronic cell counter.
The Biology of the Cell Surface was created in 1939.
The surface area of a cell is defined as the total area encompassing the perimeter of the outer cell layer. The surface area of a cell is an important part of the Surface Area to Volume Ratio in terms of the effect it has on molecules that are entering or exit the cell.
cell membrane aka plasma membrane
The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
Surface area of cell is divided volume of cell to get surface to volume ratio . If surface area is 8 cm2 and volume is 2 cm2 . The ratio would be 4:1 .
A cell's volume is the amount of material that can fit into the cell. A cell's surface area is the total amount of material that makes up the outside of the cell. The ratio of surface area to volume is the amount of surface area per unit volume of an object or collection of objects.
