For any cube with sides of length 'S':

The area of each face is S2 .

The total surface area is 6S2 .

The volume is S3 .

The ratio of surface area to volume is ( 6S2/S3 ) = 6/S .

If 'S' is 0.2, then the ratio is (6/0.2) = 30.

Note:

We're uncomfortable with this whole thing, because it deals exclusively

with the numbers, and it completely ignores the units and dimensions.

To obtain the ratio of surface area to volume, divide the surface area by the volume.


How do you calculate the surface-area-to-volume-ratio?

The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.

What happens to a cell's ratio of surface area to volume as the volume increases more rapidly than its surface area?

As volume increases surface area increase, but the higher the volume the less surface area in the ratio. For example. A cube 1mmx1mmx1mm has volume of 1mm3 surface area of 6mm2 which is a ration of 1:6 and a cube of 2mmx2mmx2mm has a volume of 8mm3 and surface area of 24mm2 which is a ratio of 1:3.


What is ratio of surface area to volume?

surface area/ volume. wider range of surface area to volume is better for cells.

What shapes have the smallest surface area per volumn?

The fewer the number of sides that a polygon has, the higher the surface area to volume ratio. This increases until the polygon has an infinite number of sides, or has become a perfect sphere, when the ratio is the smallest.


What is the surface area-to-volume ratio of a cute with a side length of 2 mm?

A "cute" cube with sides of 2mm has a volume of 23 cu.mm. = 8 cubic mm. The surface area is 2*2 each, times 6 surfaces = 24 square mm. Surface area to volume ratio is 24:8 which is 3:1 By the way, the ratio is 1:1 when the sides are 6mm (or 6cm or 6m or 6km).


What happens to a cell ratio of surface area to volume as the cells volume increases rapidly than its surface area?

The cell's ratio of surface area to volume would decrease if its volume increases more rapidly than its surface area.
