What is the surface area of a grape?
The surface area of a grape can be calculated using the formula for the surface area of a sphere, which is 4πr^2, where r is the radius of the grape. Since the shape of a grape closely resembles a sphere, you would measure the radius of the grape and plug it into the formula to find the surface area. The size of a typical grape can vary, but for a standard grape, the surface area is usually around 1-2 square inches.
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
