The same 2 to 3 because the mass is directly proportional to the volume. Recall the relationship Mass = volume x density. Here density remains constant
Area ratio = (edge-length ratio)2 Volume ratio = (edge-length ratio)3 Volume ratio = (area ratio)3/2
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
1. Calculate the surface area 2. Calculate the volume 3. Divide
You don't need the mass to get the volume. Your cube's volume = 1*2*3 = 6 cubic metres.
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 ■
I have absolutely NO idea!
Density is the ratio of mass to volume of a substance. d = rho = m / V Density generally depends upon the following : ( 1 ) Identity of the substance ( 2 ) Temperature ( 3 ) Pressure for gases
Area ratio = (edge-length ratio)2 Volume ratio = (edge-length ratio)3 Volume ratio = (area ratio)3/2
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the 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
2 two

If they have the same radius then it is: 3 to 2
The density of an object with a mass of 16 g and volume of 8 cm^3 would be 2 g/cm^3.
If you mean why does the density of an object not change when it undergoes a physical change such as a change of shape then the answer is because density is a chemical trait found by dividing the mass by the volume and if you modify the volume then the mass will also be modified for example water has a density of 1 g/cm^3 meaning if you have 3 grams of water it takes up 3 cm^3 even if you change the mass when you change the mass you are also changing the volume same goes if you change the volume you change the mass. In other words mass and volume are relative to each other and when you divide mass by volume you get a number the density the density represents a ratio for water the density is 1 g/cm^3 the ratio of mass to volume is 1:1,1/1, or 1 to 1 meaning for every cm^3 you have of water you will have an equivalent amount of grams. 1 to 1 1 part mass 1 part volume but that is just for water every substance has a density and they rarely if ever are equal.
This is called the weight density. Weight density of water, for instance, is 62.4 lb/ft^3
