The surface area is the sum of all the shapes' area
the area of such an outer part or uppermost layer
You mean a rectangular prism? Like a block of lego? Then you just need to work out the surface area of the four sides, which will be two pairs of identical rectangles. So; ((L*W)+(W*D))*2 L ______|______ / /| /____________/ |-D | | | | | / |____________|/ \ W
surface area
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
surface are of a shape means is the total area of the faces and curved surface of a solid figure.kellie edwards.
They both increase with increasing cell radius (if we model a cell as a sphere). However, the rate of increase of the surface area is in general slower (dA/dr = 8πr) compared to the rate of increase of the volume (dV/dr = 4πr2). This would mean that with increasing cell size, the surface area to volume ratio is becoming smaller and smaller, giving a cell less surface area for the transport of nutrients for a given unit volume.

Because the crystals of the table salt are smaller and the speed of solving depend on the surface area of the material (smaller crystals mean a greatest surface area); dissolution takes place at the surface of the solid.

To increase the solubility of a solution, you can heat the solvent, increase the surface area of the solute by crushing or grinding it, or stir the solution to distribute solute particles evenly. Adding a co-solvent or adjusting the pH of the solution can also help enhance solubility.
You mean to say why does the small intestine have an internal surface area, well this is because there are micro-villi which are folded finger-like projection that each increase the amount of space food can be absorbed.
the area of such an outer part or uppermost layer
S= SA and that stands for surface areas = surface area
surface area is the total outer area of a figure (I.E. a cubes surface area can be calculated by adding the area of its 4 squares)
Flaps in some cases are used to increase wing surface area. In most small single and multi-engine airplanes the flaps that are being utilitized usually plain, split or slotted, do not increase the surface area. They increase the camber (camber being the distance between the mean thickness of the wing and the line going from the leading edge to the trailing edge (called the chordline)), and also increase the coefficient of lift (or how hard the wing is working to produce lift). On most transport category airplanes they utilize what is called fowler flaps. These flaps increase the surface area of the wing by moving the flaps rearward on a track. This rearward movement increases those things stated earlier and also increased the surface area, which also produces more lift.
Villi are tine hair like projections on the surface of intestinal epithelial cells. They increase the surface area of the cells and help in the process of absorption during digestion. Villi are not restricted to humans. They are found in a variety of mammalian organisms and their primary function is to increase the surface ares for absorption
