Find the surface area of this?

If it's only the front, and assuming it's rectangular, it's 30 x 30 =900. If it is not rectangular, information is not sufficient to tell.

H*W= area\nheight times width\n\none side has a height of 8 and its width is 9 thus the area would be 72

It is similar to calculating the area. \n\nIt is a product of Length and Width (L x W).

Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h\n\n(h is the height of the cylinder, r is the radius of the top) \n\nSurface Area = Areas of top and bottom +Area of the side \n\nSurface Area = 2(Area of top) + (perimeter of top)* height \n\nSurface Area = 2(pi r 2) + (2 pi r)* h \n\nIn words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can. That's the top, the bottom, and the paper label that wraps around the middle. \n\nYou can find the area of the top (or the bottom). That's the formula for area of a circle (pi r2). Since there is both a top and a bottom, that gets multiplied by two. \n\nThe side is like the label of the can. If you peel it off and lay it flat it will be a rectangle. The area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h. \n\nAdd those two parts together and you have the formula for the surface area of a cylinder. \n\nSurface Area = 2(pi r 2) + (2 pi r)* h

I'm not sure if this is what you're asking, but if...\nd = length\nd-3 = width\n\nthen the area is d(d-3), a.k.a. d^2 - 3d .\n\nHope this helps!

you need to use some calculus.\nget an expression for the area \ndifferentiate it\nthen find when it is a maximum.

it would be 2/3 of the original surface area\n\nOriginal Cube Surface Area:\n6 sides.....one side = Length * Width\n6*L*W\n\nIf you cut it exactly in half, you have 2 sides that are still Length * Width, and 4 sides that are HALF Length * width....so u can combine those 4 halves to make 2 wholes and ur surface area will be 4 (Length*Width)'s\n\nmaking it 4/6th of the original surface area\nsimplifying gives u 2/3

tricky question... you could probably get a fair approximation by looking at a computer model of the wonders and having the computer determine the surface area based on how much mesh is required to cover the model.\n\nIRL I would probably just take a model and see how much paint is required to cover the surface, that should give you a good estimate.

area: l*w = 256\n-> 4w*w = 256\n->w(sqaure) = 64\n->w=8 (width)\n->l = 4w = 4*8 = 32(length). \n\nThere you go.

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 ^_^

Area = length x width

You have to find an area.  If ou have one foot by one foot, it is one square foot.  If the area is circular, find the area of the circle.

Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h\n\n\nr=radius\nh=height\n\nnote: the 2 after the 2 pi r is a square

The surface area of a sphere of radius 'r' is given by:\n\nsurface area = \n 4*pi*r^2\n \n\nNOTE: The value of p can never be known exactly, so surface areas of spheres cannot be calculated exactly. Common approximations for p are: 3.14, and 22/7. \n\nExample 1  if 'r' = 5 for a given sphere, and p = 3.14, then the surface area of the sphere is:\n\nsurface area = 4*pi*r^2\n\n         = 4 × 3.14 × 25\n\n         = 314

It depends what it looks like.\nWithout seeing the actual picture I cannot find the area.

Surface Area of a Cylinder = 2 pi r 2 + 2 pi rh. (h is the height of the cylinder, r is the radius of the top).\n\nSurface Area = 2(pi r 2) + (2 pi r)* h \n\nSurface Area = Areas of top and bottom +Area of the side
