The ratio is 1/2 square meter per cubic meter.
Perhaps if you read the question properly, you would not have to ask the question!
0.5m-1
It is not possible to have a sphere with a surface are of 300 metres squared and a volume of 500 metres cubed. A surface area of 300 sq metres would imply a volume of 488.6 cubic metres or a shape that is non-spherical!
0.6 is the surface area to volume ratio.
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
0.6 m-1 is the ratio of surface area to volume for a sphere.
Perhaps if you read the question properly, you would not have to ask the question!

0.4 m-1 is the ration of surface area 588m2 to volume 1372m3 for a sphere.
It appears to be: 3 to 5

0.4 m-1 (Apex)
0.6 is the surface area to volume ratio.
The ratio of surface area to volume for a sphere is constant and equal to 3/r, where r is the radius. Given the measurements, you can calculate the radius of the sphere using the formula for volume of a sphere (V = 4/3 * π * r^3) and then find the ratio as 3/r.
-- 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)
The ratio is 300 m2/500 m3 = 0.6 per meter.(Fascinating factoid: The sphere's radius is 5 m.)
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
