In many crafts and trades an understanding of surface and volume are quite fundamental to the practice. Consider the plastering of a building, or the quantity of frosting needed for a cake. Both need to know the area surface of the object, and also need to know the volume of the surfacing material. With more practice these will become familiar and comfortable concepts.
To obtain the ratio of surface area to volume, divide the surface area by the volume.
surface area/ volume. wider range of surface area to volume is better for cells.
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.
Volume=area * length of that surface
surface area divided by volume
Volume does not, surface area does.
surface area/ volume. wider range of surface area to volume is better for cells.
To find the ratio of surface area to volume, we divide the surface area by the volume. Given a surface area of 588 and a volume of 1372, the ratio is ( \frac{588}{1372} ), which simplifies to approximately 0.429. Thus, the ratio of surface area to volume is about 0.429:1.
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.
Think of surface area as your skin and volume as all the contents inside your body. So they relate because surface area can hold volume or volume could be inside the surface area.
To find the ratio of surface area to volume for the sphere, you divide the surface area by the volume. Given that the surface area is 588 and the volume is 1372, the ratio is ( \frac{588}{1372} \approx 0.428 ). Thus, the ratio of surface area to volume for the sphere is approximately 0.428.
