What is the surface area of a grape?
A grape is closest to a sphere. 4*pi*r*r is the surface area. Measure the grape from side to side the take half of that for the radius. The closer the grape is to a sphere the more accurate it is. The more it is to an ovoid the less it will be accurate.
What shape is even more compact than a cube?
A sphere.
How does surface area effect solubility?
As the surface area of a solute increases, so does its solubility. This is because there is more area for the solvent to contact the solute and thus the solvent is able to interact with more of the solute at one time and dissolve it quicker. Think about a cube of sugar and a sheet of sugar, each the same mass. The sheet will dissolve quicker in water because so much of it is already interacting with the water molecules. The cube will not dissolve as fast because there are still molecules of sugar on the inside of the cube that will have to wait to interact with the water molecules.
How do you find a curved surface area of a shape?
It depends on the shape. If it is a sphere or an ellipsoid it is relatively easy. If it is a more exotic shape, you have some serious integration to carry out. It is not clear from the question which of these problems you are trying to solve.
Which has more surface area?
you might want to be a bit more specific =P
What is bigger the surface area of a sphere or the surface area of a cube if they have the same volume?
surface area of sphere = 4πR2 volume of sphere = 4/3πR3 surface area of cube = 6s2 volume of cube = s3 since volumes are equal then s3 = 4/3πR3 s = [cube root (4/3π)] R surface area ofcube = 6 (cube root( 4/3π) times R)2 surface area sphere = 4πR2= 12.56 R2 surface area cube = 15.44 R2 So a sphere has less surface area than a cube with the same volume. Where R= radius of the sphere s=length of side of the cube Sorry,calculation above is now corrected - same equations, earlier made math error - cube has more surface area as you can see
As the radius of a sphere gets larger which of the spheres measurements increases more the surface area or the volume?
The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)
Why is the half cube has more surface area than cube?
because
Does a sphere shaped ice cube melt faster than a regular shaped ice cube?
A cylinder shaped ice cube will melt faster because it has a greater surface area than the rectangle-shaped ice cube has. Cubes of ice with less surface area will melt slower. Ice that has very low surface area has more ice concealed inside than it does on the outside. Therefore, ice cubes that have more surface area will melt faster... I hope this will help you.. :) ..
How are a cube and a sphere different?
a cube and a sphere are different because is more of a square shape and a sphere is cylindrical
How much faster does volume increase compared to surface area?
Hi,In general when something becomes larger, the surface area to volume ratio decreases. The analogy of a cube is indeed a useful way to think about it. I'll try to put it in more general terms.Cubes are a great example to talk about because their surface area and volume are really easy to calculate. The surface area of a cube is the length x the width x the number of sides (six sides, in the case of a cube). The volume of a cube is the length x width x volume.So, say we have a cube with a side length of three. The surface area is going to be 3x3x6 = 54. The volume is going to be 3x3x3 = 27, for a ratio of 54:27, or 2:1//Another contributor does not think you should make a ratio of different dimensions (area and volume)//Surface area increases as the square of a dimension, volume increases as the cube of a dimension.Example:A sphere (ball)Diameter = 1 unitIncrease diameter to twice the size: New diameter = 2Area of new sphere = 4 times the area of the initial sphereVolume of the new sphere = 8 times the volume of the initial sphere
A living cell is not a simple geometric shape like a sphere or a cube. What sort of weird cell shape might increase the ratio of surface area to volume Would you be able to test this more complex shap?

Does the shape of an ice cube affect how long it takes the ice cube to melt?
Yes, absolutely. Heat transfer from the surrounding environment into the ice cube causes it to melt. The greater the rate of heat transfer INTO to ice cube, the faster it will melt. The greater the surface area of the ice cube, in relation to it size, the faster the melting will occur. The ideal shape for the least heat transfer [and this is true for cold or hot objects] is a SPHERE. A sphere has the minimum surface area for the mass of the object. Any shape other than a sphere has more surface area for the mass, an will melt faster. The thinner more spreak out ice will melt faster melting consumes enerhy inthe form of heat. The amount of energy needed is the proportional of the ice water. The heat applied to it can be radiation or matter. Johnson Kevin, Ohio
How can you increase the surface area of a solid reactant?
It exposes more of the solid to whatever you want to mix it with so that whatever you are doing, whether it be a physical or chemical change, will take place more rapidly.
Does a larger surface area makes diffusion happen more quickly?
yes. Lets for example take a potato cube put in a jar of water. if the potato cube has a large surface area, then more of its surface will be exposed to water molecules, meaning that more can diffuse into it more quickly.
Who discovered the formula for a sphere?
What's more important is knowing the formulae for a sphere which are:- Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
