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

weeeeeb [17]

Answer:

Ratio = $3\times 10^5$

Explanation:

Side of a cube, a = 20 µm

$a=20\times 10^{-6}\ m$

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 :

$R=\dfrac{6a^2}{a^3}\\\\R=\dfrac{6}{a}\\\\R=\dfrac{6}{20\times 10^{-6}}\\\\R=3\times 10^5$

So, the ratio of the surface to volume ratio of the cell $3\times 10^5$ .
