Question

PLEASE I NEED THIS ASAP If you had a cell that was cube-shaped with a side length of 20µm, calculate the surface to volume ratio of the cell. Round your answer to the tenths place.

Answer 1

0.3

Step-by-step explanation:

I got it right on my AP Bio assignment on edge

Answer 2

Ratio =
`3* 10^5`

Step-by-step explanation:

Side of a cube, a = 20 µm

`a=20* 10^(-6)\ m`

The surface area of a cube, A = 6a² (a is side of the cube)

The volume of a cube, V = a³

The ratio of the surface to volume ratio of the cell will be given by :

`R=(6a^2)/(a^3)\\\\R=(6)/(a)\\\\R=(6)/(20* 10^(-6))\\\\R=3* 10^5`

So, the ratio of the surface to volume ratio of the cell
`3* 10^5`.
