0.6 m-1 is the ratio of surface area to volume for a sphere.

0.6 is the surface area to volume ratio.

because the surface area is spread out over the volume of mass

-- The ratio of 588 to 1,372 is 0.4286 (rounded) -- A sphere with surface area of 588 has volume closer to 1,340.7 . (rounded)

1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio

a sphere

Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared to the same volume of the material. For example, let us consider a sphere of radius r: The surface area of the sphere will be 4πr2 The volume of the sphere = 4/3(πr3) Therefore the surface area to the volume ratio will be 4πr2/{4/3(πr3)} = 3/r It means that the surface area to volume ration increases with the decrease in radius of the sphere and vice versa.

A sphere can either have a surface area of 432 m2 but not a volume of 864 m3, or it can have a volume of 864 m3 but not a surface area of 432 m2.

-- "864m square" is not a volume. "864m cubed" is a volume.-- A sphere can't have those measurements.If it's really a sphere with surface area of 432 m2, then its volume is 844.3 m3.If it's really a sphere with volume 864 m3, then its surface area is 438.7 m2.-- The answer to the question is: The ratio of 432 m2 to 864 m2 is 0.5 .-- If those are really an area and a volume, then the ratio of 432 m2 to 864 m3 is 0.5 per meter.

Well, first of all, that's no sphere.-- A sphere with surface area = 300 has volume = 488.6.-- A sphere needs surface area of 304.6 in order to have volume = 500.But this is just a ratio exercise, not a geometry problem, so we'll just use the numbersgiven in the question. It's just some sort of wacky humongous paramecium:Surface area = 300Volume = 500Ratio of (surface area)/(volume) = 300/500 = 0.6 .

0.4 m-1 is the ration of surface area 588m2 to volume 1372m3 for a sphere.

The ratio of surface area to volume increases. The area of a sphere is proportional to its radius squared. Volume is proportional to radius cubed. As the radius increases, the volume increases more than the surface area. As the radius decreases, the volume decreases more than the surface area, so the ratio of surface area to volume increases.
