Question 5 of 10

Human epithelium contains a layer of cube-shaped cells. If the length, height,
and width of such a cell is 1 micrometer (um), what is the cell's ratio of
surface area to volume?

Answer 1

The ratio is 6 to 1

Step-by-step explanation:

1. a 6 sided cube of 1 mM has a volume of L * W* H (1*1*1=1) 1 mM.

2. a 6 sided cube has a surface area of one face surface area times 6 or (L * W) * 6 = 1mM * 1 mM * 6 = 6

so the ratio of surface to volume is 6/1.
