How is Acreage calculated? Is elevation a factor?

Acre is a measurement of area; therefore it is calculated by multiplying length with breadth. Thus, the word square will always be used. Such as square meter, square yards square inches and square kilometers etc.\nWhile calculating an area of a given place elevation is not taken in account. \nNow, the following table will help you to understand The ACRE you have in mind.\ni) 144 inches = 1 square foot= 12inches multiplied by 12 inches.\nii) 9 square feet = 1 square yard = 3feet multiplied by 3feet. (3feet = 1yard).\niii) 4840 square yards = 1 Acre.Since acre it self is an area measurement only; the word squre is not used

The volume of rainfall can be calculated as hectare-mm or acre-inches in an area or watershed.\n\nThe equation is:\nrainfall volume = hectares in watershed x mm of rain\nrainfall volume = acres in watershed x inches of rain

Yes its the area...say of the parking lot.  This is the Rational Method.  It looks alot like darcy's law.  It is very simple and easy to use.  However, for undeveloped areas....forested, grass...try the SCS Method.  It is a little more complicated but produces better results.

"Square feet" are used to measure area and "cubic feet" are used to measure volume. These are quite different concepts and there is no way to change one into the other. You can convert cubic feet to gallons, (one gallon is approximately 0.1336 cubic feet) or square feet to acres (one acre is 43,560 square feet) but not square feet to cubic feet.\n\nIf you were covering an area with a depth, then we can convert.  see below:\n\nhow many cubic yards of soil is needed to cover 750 square feet at a height of 3 inches?\n--------------------------------------------------------------------------------\nSince you want the volume in cubic yards I would first convert all the measurements to yards. There are 3 feet in a yard and hence 32 = 9 square feet in a square yard. Thus\n\n750 square feet is 750/9  = 83.33 square yards.\n\nThere are 36 inches in a yard so\n\n3 inches is 3/36  = 0.0833 yards.\n\nThus the volume of soil needed is\n\n83.33  0.0833 = 6.9 cubic yards.

you can get an approximate value by finding your location on Google Earth.\nrun the cursor over your house and it will display the elevation (in feet) at the bottom of the screen.\n\nMore precise: unless you know a surveyor, try  GPS.\nIt will give accuracies as good as .02m (under an inch)

1 acre = 43,560 square feet (feet length times width)

Let us assume that we require a cone with d as bottom circle dia, h as vertical height which are the known factors. Let l be the slant height of the cone which is equal to Square root of (h^2+(d/2)^2). To arrive the cone we have to make a sector with l as radius and A as angle of the sector. \nl is already calculated. A is calculated as follows:\nA = pi()*d/l which is obtained in radians; \nTo convert it to degrees, multiply A with 180 and divide by pi();\nSo we get A in degrees and l, from which we can get a sector. By connecting the two slant heights together we can get a cone with dia d and height h.

A parcel refers to one piece of land.  could be any size.  Here's some neat-to-know info:  208' x 208' = 1 acre.\n43,560 square feet = 1 acre\nIf your parcel is, for example, 100' x 220' it about 1/2 acre \n(100 x 220 = 22,000 square feet divided by 43,560 = approx .5)

Area in feet = 80*171 = 13680 square feet\n\n1 square foot = 0.000 022 957 acre\n13 680 square feet = 0.314 049 587 acre\n\n3/4 acres = 0.75 acres\n1/2 acres = 0.5 acres\nSo 0.314 acres is neither.

I know this sounds stupid, but it depends on the size of the lots.\n\nA developer can make them whatever size he wants, but most are between 1/4 to 1/2 acre.  1/3 acre lots are pretty much standard here.

An acre is the name of a unit of area in a number of different systems, including Imperial units, and United States customary units. The most commonly used acres today are the international acre and, in the United States, the survey acre. There are 43,560 square feet in an acre.\n\nThere are always 4,840 square yards in an acre. Because of alternative definitions of a yard, the exact size of an acre also varies. Related units of length are the acre's length of one furlong (220 yards) and the acre's breadth of one chain (4 rods or 22 yards).\n\nThe acre is often used to express areas of land. In the metric system, the hectare is commonly used for the same purpose. An acre is approximately 0.4 hectares.\n\nOne acre is slightly less than 91 yards on an American football field, with the full field, including the end zones, covering approximately 1.32 acres.

Lot is not a standard size like acre or hectare.\n\nA lot can be 20' by 20' or 10' by 350' or any other number of combinations.

The method is entirely dependent on what you know about the triangle in the first place.  If you know the 3 sides, you can use Steve's law for the altitude; ex: (alt to side c) = sqrt(4a^2b^2-(a^2+b^2-c^2)^2) / 2c\n\nIn general, the altitudes of a triangle intersect at a point called the orthocenter, whose location is described in detail at\nhttp://www.cut-the-knot.org/triangle/altitudes.shtml
