The maximum volume with the least surface area is enclosed in a sphere.
That's why soap bubbles, balloons, and stars settle into spherical shapes.

Is it better to have a big surface area with a small volume or small surface area with a big volume?
It doesnt matter at all, because the volume immobilizes the size of the needed surface to cover the whole thing in order to view it as a separated 'space'. The shape of the whole thing has no influence at all. The bigger the volume, the larger the surface & vice versa.
What are adaptations for the surface area to volume ratio?
When an animal for example an elephant has a large surface area to volume ratio (big animals) it can lose heat easier which is an adaptation to survive the climate in which they live
How does your body adopt surface area to volume ratio to help exchange gases-?
The skin surface is not large enough for big creatures such as humans; therefore we have structures in our lungs that greatly increase the surface area.
Consider eight little spheres of mercury each with a diameter of 1mm When they coalesce to form a single sphere how big will it be How does its surface area compare with the total surface area of?
The total volume of the new sphere will be 4 times less than the sum of all eight individual volumes. The total surface area will be about half than the total surface area of all individual balls.
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.

What keep a cell from getting too big?
surface area -to- volume ratio
What is cell volume?
The volume is how much space is inside the cell. The ratio is the surface area divided by the volume. This indicates how much surface area is available compared to how big the cell is.

What problems does a big cell have surface area to volume ratio?
The main problem with a big cell is that the ration of the surface to the volume is small. That means that there is a lot of stuff inside the cell that needs water, electrolytes, energy, etc, and if the cell doesn't have a very big surface area, it will be difficult for enough of those needed things to enter the cell. This is why there are not very many large single-celled organisms. I think amoebas are among the largest single-celled organisms, and can be visible to the naked eye.
Why do cells get so big than divide?
Cells are dependent on the ration between surface area and volume. as the cels get bigger the ratio decreases, meaning that the volume gets larger faster than does the surface area. they cant survive past a certain point, because the nutrients that permeate the membrane have a harder time diffusing throughout a larger volume with a comparatively smaller surface area. this is why cells divide: the volume splits in half, but the surface area stays the same.
What is the surface area to volume ratio in a cell and why is it importa NT?
The surface area to volume ratio is how big the cell's membrane's area is compared to the volume of everything inside the cell. If the volume becomes too large, the cell will not be able to release waste or receive necessary nutrients as easily. Plus, the cell's DNA can't keep up with the cell.
How do surface area and volume limit the size of cells?
The bigger the volume of the cell, the smaller the surface area to volume ratio, or to put it more simply, big cells have more inside bits which have no contact with the outside. The substances which need to pass into and out of the cell can only do so through the surface. This means that if a cell is too big it simply cannot exchange things (such as oxygen and carbon dioxide) with the outside fast enough to survive.
How does cell size affect cell survival?
Diffusion of such such as oxygen would become more difficult in big cells, where the surface area/volume ratio is too big. Cells or part of cells can get very big, but the ratio would have to be compensated for, usually by lessening the volume per surface area, as is the case of a long neuron's axon.
Relate ratio of surface area to volume to cell growth and cell division?
When a cell is too big, it makes it more difficult for it to bring in proteins and protect itself from disease, not to mention that the membrane will become stretched and almost useless. When a cell is too large it will usually divide to cause the optimal situation; more surface area than volume. With more surface area and less volume the cell is easier to maintain and protect.
Which has a great surface area a cube that is 2 cm x 2 cm on a side or eight cubes that are each 1 cm x 1 cm on a side?
The eight little cubes, combined, have the same volume as the single big cube has, but they have double the surface area of the big one.
