When the volume of a cell increased its surface area?

When the volume of a cell increased its surface area?
by

1 Answer

Answer :

increases:by approximately the square of the cube root of the volumeincrease(that would be exact if the cell was a sphere).Or, in other words,if you double the size (diameter) of a cell.its surface area increases by a factor of 4,and it volume increases by a factor of 8.
