what does approximate surface area of the solid mean?

look at the link attached.  it's hard for me to explain, but i know what it is.

A\nB would be for a polished surface,\nC and D are never true (although on a macroscopic scale it can appear that they are).

in a 2d object or representation, it would be the area. In a 3 dimensional object it would be the volume.

I'm guessing that you're asking what does it mean to say something is 2.5 dimensional, as opposed to 2 dimensional or 3 dimensional.  \n\nAnytime you have a fractional dimension like that, you're dealing with a fractal.  That's where the word "fractal" comes from.  The dimension for an object that is self-similar at many size scales in a complex way can be thought of as an extension of the obvious fact that a uniform object of unit length d in two dimensions has an area of d^2.  In three dimensions, a uniform object of unit  d (a cube with sides d units long) has a volume of d^3, and so on.  \n\nSo, you can generalize this concept and say that something has the dimensionality of whatever power the scale along one axis has to be raised to in order to give the area/volume/whatever.   Since a fractal object has repetition at all scales of some sort of complex pattern, the relationship between scale and total size, the dimensionality, is a non-integer.\n\nSo, for example, if you had a volume which had been "Swiss cheesed" by some sort of algorithmic removal of sub-volumes, and sub-volumes of the remaining volumes, and so on, and so on, to make a fractal sponge, it would have a dimensionality between 2 and 3.

Area is the measure of the two-dimensional size of any shape. Area is calculated in different ways for different shapes, for example, for a rectangle A = l x h (length multiplied by height), for a triangle A = 1/2 b x h (half of the base multiplied by the height), and for a circle A = pie x r^2 (pie multiplied by the square of the radius).\n\nPerimeter is simply the distance around a figure, or the total length of the border of a shape. Again, perimeter is calculated in different ways for different shapes. For a rectangle, P = 2 (l + h) and for a circle the perimeter is called the 'circumference', nd calculated by the formula C = 2 x pie x r.

the surface area is (1/2 X perimeter of base X slant height)\nthe total surface area is ((1/2 X perimeter of base X slant height) + (area of base))

Not considering the spheric harmonic of high orders I would have to tell you that my physics spirit tell the surface area  is what counts and there you could have k0.2Pi.R=2Pi <=>k0=1/R\nk1=1/(2R), k2=1/(distance of the 3 points more away from each other)........................

If by area you mean "Surface area" then\nSA(sphere) = 4(pi)(r)^2\nand\nV(sphere) = 4(pi)(r)^3/3\n\nSince SA = 196 cm^2, then\n\n196cm^n = 4(pi)r^2\nr^2 = 49/pi\nr = 7/sqrt(pi) or approx. 3.949 cm\n\nfor the volume,\nV = 4(pi)(r)^3/3\nV = 4(pi)(7/pi^0.5)^3/3\nV = (4pi/3)(343/pi^1.5)\nV = (1372/(3pi^.5)) or approx. 258.02 cm^3\n\n^_^ Hope this helps ^_^

It's the formula for the area of a regular polygon\n\nArea = 1/2 times apothem times perimeter\n\n(apothem = perpendicular distance from center to midpoint of a side)

Think of the first as the area of a flat round plate sweeping out the inside of the figure you get from the rotation.  What will be its area? πr² where the r is the y value of √(9 + X²).  That changing area will sweep out the volume from whatever the limits are (you don't say), so it's the integral of π(√(9 + X²))², or π(9 + X²).\n\nIn the second case, the thing sweeping out the volume is the surface area of a cylinder as its radius grows.  Thats the circumfrence of the base times the height.  The circumfrence is 2πr where r is the X value and the height is the difference between Y = x and Y = X/2.  So it's the integral from 0 to 2 of:\n\n   2πX(X-X/2).\n\nThinking of an area sweeping thru the volume helps.

To cacultate the surface area, you first need to know what shape it is.  follow this link for many different equations and find the one for your shape.

100 and 1000, respectively. Surface area is proportional to the square of the radius, so if a cell's surface ares is 4πr², then the surface are of a cell with 10 times the radius is 4π(10r)² = 100(4πr²). Similar logic applies to volume (which is proportional to the cube of the radius).

initial surface area=6a^2\nnew surface area=2[2a^2+4(a^2/2)]\n=2*4a^2=8a^2\nit will be 4/3 times the original surface area

Density is mass/volume\n\nYou've given 3 dimensions of an object, does that mean that it's a rectangular solid?  If so, then vol = L*H*D.

YOU ARE RIGHT. THE SURFACE OF THE PARTICLE OR OBJECT HAS TO BE UNEVEN OR ROUGH SURFACE

to calculate the area of a 2-dimensional space you always multiply length x width, or in this case height\n\nC

With the limited info in this question I'm making assumptions. I believe it means that your baking vessel is a square, each side being 28cm.
