what is volume?

Answer 1

Cube
Multiply the length by the width.
Multiply the base (length x width) by the height.
Sphere
Find the radius (point from middle of sphere to anywhere on the edge) or half of the diameter (straight line which goes through the middle point of the sphere and touches both sides).
Multiply the radius by itself twice (e.g. 5x5x5).
Multiply that number by 3.14 (an approximation of pi).
Multiply that number by 4.
Divide that number by 3.
Cylinder
Find the radius of the end circles
Multiply the radius by itself once (e.g. 5x5).
Multiply that number by 3.14
Multiply that number by the height of the cylinder
Cone
Same as above (radius is the radius of the base circle)
Divide by 3
Irregular Solid
Learn Calculus
Apply the disc or washer method to approximate the volume
Find one dimension of the object (eg. its length), call that 'x'.
Find the area of a cross section of the object, taken perpendicular to the known dimension.
Find how the area of the cross section varies, as a function of it's distance along x from one end, call that F(x).
Take the integral of F(x) as x varies from 0 to the length of the object
Scientific Method
For a real object (not something you have on paper), you can use a volumetric flask or graduated cylinder to measure its volume. If you don't mind getting it wet, just see how much water it displaces to get its exact volume. Almost calculation-free!

Pour enough water into the flask to immerse the object. If you're not sure on how much, drop the object in first, pour the water over it, and then take it out.
Measure the initial water level v1. Get this as precisely as possible, and write it down or something! Make sure not to spill any water or let more in.
Drop the object you're measuring into the flask. If it floats, you can use something to weigh it down. Just measure your new weight's volume separately and subtract it later.
Measure the new water level. Call this v2.
The volume of the object is equal to the difference of the initial and final volumes. v = v2 - v1

Answer 2

The definition of volume is the amount of space an object takes up. It is measured by V=l x w x h, or of a liquid with a graduated cylinder.
A gas takes up what ever volume you put it in.
a liquid and solid keep their volume.
The volume of an irregular solid can be found by water displacement.

There is also the volume or loudness of sound which is measured in decibels.

Answer 3

Volume is calculated in different ways for different shapes, but in plain english it is the amount of total space the shape possesses.

A cube for example, the volume is calculated by multyplying width by height by length(l x w x h). the answer will tell you how much space you have within that cube.

Answer 4

volume 2 is a much better movie, besides the actual incontrovertible fact that both are favorites of mine. EDIT: the human beings that did not like 2 because it changed into "dull" are morons. countless the human beings who say which have the recommendations of a small baby.

Answer 5

The amount of 3-dimensional space occupied by an object

Answer 6

the volume represents the space an object occupies in space. by convention it is measured in liters or cm3.

Answer 7

simply:

hight x width x length = volume

Answer 8

The volume of a solid object is a numerical value given to describe the three-dimensional concept of how much space it occupies. One-dimensional objects (such as lines) and two-dimensional objects (such as squares) are assigned zero volume in the three-dimensional space.

Volumes of straight-edged and circular shapes are calculated using arithmetic formulas. Volumes of other curved shapes are calculated using integral calculus, by approximating the given body with a large amount of small cubes or concentric cylindrical shells, and adding the individual volumes of those shapes. The generalization of volume to arbitrarily many dimensions is called content.[citation needed] In differential geometry, volume is expressed by means of the volume form.

Volume and Capacity are sometimes distinguished, with capacity being used for how much a container can hold (with contents measured commonly in litres or its derived units), and volume being how much space an object displaces (commonly measured in cubic metres or its derived units).

Volume and capacity are also distinguished in a capacity management setting, where capacity is defined as volume over a specified time period.

Volume is a fundamental parameter in thermodynamics and it is conjugate to pressure.

Volume formulae
Common equations for volume:
Shape Equation Variables
A cube: s = length of a side
A rectangular prism: l = length, w = width, h = height
A cylinder (circular prism): r = radius of circular face, h = distance between faces
Any prism that has a constant cross sectional area along the height**: A = area of the base, h = height
A sphere: r = radius of sphere
which is the first integral of the formula for Surface Area of a sphere
An ellipsoid: a, b, c = semi-axes of ellipsoid
A pyramid: A = area of base, h = height from base to apex
A cone (circular-based pyramid): r = radius of circle at base, h = distance from base to tip
Any figure (calculus required) h = any dimension of the figure, A(h) = area of the cross-sections perpendicular to h described as a function of the position along h
this will work for any figure (no matter if the prism is slanted or the cross-sections change shape).

The volume of a parallelepiped is the absolute value of the scalar triple product of the subtending vectors, or equivalently the absolute value of the determinant of the corresponding matrix.

The volume of any tetrahedron, given its vertices a, b, c and d, is (1/6)·|det(a−b, b−c, c−d)|, or any other combination of pairs of vertices that form a simply connected graph.


[edit] Volume measures: USA
U.S. customary units of volume:

U.S. fluid ounce, about 29.6 mL
U.S. liquid pint = 16 fluid ounces, or about 473 mL
U.S. dry pint = 1/64 U.S. bushel, or about 551 mL (used for things such as blueberries)
U.S. liquid quart = 32 fluid ounces, or about 946 mL
32 fluid ounces or two U.S. pints, or about 950 mL

U.S. dry quart = 1/32 U.S. bushel, or about 1.101 L
U.S. liquid gallon = 128 fluid ounces or four U.S. quarts, about 3.785 L
U.S. dry gallon = 1/8 U.S. bushel, or about 4.405 L
U.S. (dry level) bushel = 2150.42 cubic inches, or about 35.239 L
The acre foot is often used in measuring the volume of water in a reservoir or an aquifer. It is the volume of water that would cover an area of one acre to a depth of one foot. It is equivalent to 43,560 cubic feet or exactly 1233.481 837 547 52 m³.

cubic inch = 16.387 064 cm3
cubic foot = 1,728 in3 ≈ 28.317 dm3
cubic yard = 27 ft3 ≈ 0.7646 m3
cubic mile = 5,451,776,000 yd3 = 3,379,200 acre-feet ≈ 4.168 km3

[edit] Volume measures: UK
The UK is undergoing metrication and is increasingly using the SI metric system's units of volume, i.e. cubic meter and liter. However, some former units of volume are still in varying degrees of usage:

Imperial units of volume:

UK fluid ounce, about 28.4 mL (this equals the volume of an avoirdupois ounce of water under certain conditions)
UK pint = 20 fluid ounces, or about 568 mL
UK quart = 40 ounces or two pints1.137 L
UK gallon = 4 quarts, or exactly 4.546 09 L
The quart is now obsolete and the fluid ounce extremely rare. The gallon is only used for transportation uses, (it is illegal for petrol and diesel to be sold by the gallon). The pint is the only Imperial unit that is in everyday use, for the sale of draught beer and cider (bottled and canned beer is sold in SI units) and for milk (this too is increasingly being sold in SI units). 1 cup


[edit] Volume measures: cooking
Traditional cooking measures for volume also include:

teaspoon = 1/6 U.S. fluid ounce (about 4.929 mL)
teaspoon = 1/6 Imperial fluid ounce (about 4.736 mL) (Canada)
teaspoon = 5 mL (metric)
tablespoon = ½ U.S. fluid ounce or 3 teaspoons (about 14.79 mL)
tablespoon = ½ Imperial fluid ounce or 3 teaspoons (about 14.21 mL) (Canada)
tablespoon = 15 mL or 3 teaspoons (metric)
tablespoon = 5 fluidrams (about 17.76 mL) (British)
cup = 8 U.S. fluid ounces or ½ U.S. liquid pint (about 237 mL)
cup = 8 Imperial fluid ounces or ½ fluid pint (about 227 mL) (Canada)
cup = 250 mL (metric)
