First measure the surface area in m2. Then the mass in kg. Divide the surface area by the mass. Now you have your surface area to mass ratio as m2/kg, or verbally, square metres of area per kilogram of mass.
So how to measure the surface area? Well, if it is a human body you can calculate it using one of the common formulae available, such as Mosteller or Dubois and Dubois, from mass and height.
If it is an odd-shaped inanimate object, you could measure the m2/litre properties of a sticky liquid, then measure how much volume is used to coat the object. You could experiment with some simple shapes first to validate your method.

How do you calculate surface area to volume ratio?
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
How do you compare the surface are to volume ratio of cells of different size?
You need to:* Calculate the surface area * Calculate the 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.
How do you find what the ratio of surface area to volume for a sphere is?
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
How do you work out suface area to volume ratio?
1. Calculate the surface area 2. Calculate the volume 3. Divide
How would you calculate the surface area t volume ratio?
Divide the total surface area of the cell by the cell's volume.
How would you calculate by surface area to volume ratio?
Multiply the surface area by the volume Also stop cheating ur hw
How do you calculate a ratio from a percent?
Formula to calculate the ratio
How do you calculate the volume to surface area ratio?
Divide the surface area by the volume..Its not a fixed ratio, its an algorithm, either way.sa = surface areav = volume>volume from surface area:v = 1.333 * pi * (square root ( sa / ( 4 * pi) ) )3>surface area from volume:sa = 4 * pi * ( cube root ( ( (v * 0.75 ) / pi ) ) )2Answer:The above is overly complicated, partially incorrect and partly irrelevant.It IS a fixed ratio: that of surface area to volume.And where does pi come into it?Is it not possible to calculate the surface area to volume ration of a cube? That doesn't require pi.Thats right.The ratio however doesnt hold for a different radius.The algorithms are correct should you need to caculate one value from the other.Example:r = 1 , ratio = 3.0r = 2 , ratio = 1.5r = 3 , ratio = 1.0
What is meant by surface area to volume ratio?
Surface area to volume ratio is defined as the amount of surface area per unit volume of either a single object or a collection of objects. The calculation of this measurement is important in figuring out the rate at which a chemical reaction will proceed.
How would you calculate the surface area to volume to ratio?
surface area to volume ratio can be solved by solving the surface are of something and the volume of something then putting them togetherEXAMPLE: if it is a cube with 4 cm on each side it would be 6(4)^2 = 6(16)=96cm and volume would be 4^3= 64 so ratio would be 96:64 which can be simplified 3:2 or 3 to 2
Calculate the surface-area-to-volume ratio of a 1 mm cube and a 2 mm cube Which has the smaller ratio?
1mm cube has volume of 1mm3 and a surface area of 6*(1*1) = 6mm²2mm cube has a volume of 8mm3 and a surface area of 6(2*2)=24mm²Ratio for 1mm cube is 6-1 and ratio for 2mm cube is 3-1 ■
