Geometric relationships between surface area and volume. In this diagram, cells are represented as boxes. Using arbitrary units of length, we can calculate the cell’s surface area (in square units), volume (in cubic units), and ratio of surface area to volume. The smaller the cell, the higher the surface–to–volume ratio. A high surface–to–volume ratio facilitates the exchange of materials between a cell and its environment.
