The physical characteristics of a cell influence how it functions. For example, the surface area and volume of a cell affect how efficiently waste is removed from the cell via diffusion.
The table below shows data for four different cuboidal cells.
Cuboidal cell Side length (\mu\text{m}μmmu, start text, m, end text)
Cell A 222
Cell B 444
Cell C 666
Cell D 888
Surface area of a cube: A = 6s^2A=6s
2
A, equals, 6, s, squared
Volume of a cube: V = s^3V=s
3
V, equals, s, cubed
Using the information from the table, what is the surface-area-to-volume ratio for the cuboidal cell that removes waste via diffusion most efficiently?
