The volume of any solid, liquid, or gas is how much three-dimensional space it occupies, often quantified numerically. In mathematics the dimension of a Space is roughly defined as the minimum number of Coordinates needed to specify every point within it One-dimensional figures (such as lines) and two-dimensional shapes (such as squares) are assigned zero volume in the three-dimensional space. Classification A square (regular Quadrilateral) is a special case of a Rectangle as it has four right angles and equal parallel sides

Volumes of straight-edged and circular shapes are calculated using arithmetic formulae. 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 European Space Agency 's INTErnational Gamma-Ray Astrophysics Laboratory ( INTEGRAL) is detecting some of the most energetic radiation that comes from space A cube is a three-dimensional solid object bounded by six square faces facets or sides with three meeting at each vertex. A cylinder is one of the most basic curvilinear geometric shapes the Surface formed by the points at a fixed distance from a given Straight line, the axis The volume of irregularly shaped objects can be determined by displacement. In Fluid mechanics, displacement occurs when an object is immersed in a Fluid, pushing it out of the way and taking its If an irregularly shaped object is less dense than the fluid, you will need a weight to attach to the floating object. A sufficient weight will cause the object to sink. The final volume of the unknown object can be found by subtracting the volume of the attached heavy object and the total fluid volume displaced.

The generalization of volume to arbitrarily many dimensions is called content. In Mathematics, a content is a Real function \mu defined on a Field of sets \mathcal{A} such that \mu(A\in\ In differential geometry, volume is expressed by means of the volume form. Differential geometry is a mathematical discipline that uses the methods of differential and integral Calculus to study problems in Geometry In Mathematics, a volume form is a nowhere zero differential ''n''-form on an n - Manifold.

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). The litre or liter (see spelling differences) is a unit of Volume. CM3 redirects here If you were looking for the 3rd game in the Cooking Mama series abbreviated as CM3 see here. The volume of a dispersed gas is the capacity of its container. If more gas is added to a closed container, the container either expands (as in a balloon) or the pressure inside the container increases. Pressure (symbol 'p' is the force per unit Area applied to an object in a direction perpendicular to the surface

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. In Physics, thermodynamics (from the Greek θερμη therme meaning " Heat " and δυναμις dynamis meaning " In Thermodynamics, the Internal energy of a system is expressed in terms of pairs of conjugate variables such as temperature/entropy or pressure/volume Pressure (symbol 'p' is the force per unit Area applied to an object in a direction perpendicular to the surface

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. Properties Any of the three pairs of parallel faces can be viewed as the base planes of the prism This article is about mathematics See Lawson criterion for the use of the term triple product in relation to Nuclear fusion. In Algebra, a determinant is a function depending on n that associates a scalar, det( A) to every n × n

A sphere (from Greek σφαίρα - sphaira, "globe The European Space Agency 's INTErnational Gamma-Ray Astrophysics Laboratory ( INTEGRAL) is detecting some of the most energetic radiation that comes from space

The calculation for the volume of a sphere with center 0 and radius r is as follows.
The radius of the circular slabs is  y = \sqrt{r^2-x^2}
The surface of the circular slab is  \pi \cdot y^2
The volume of the sphere can be calculated as  \int_{-r}^r \pi(r^2-x^2) \,dx
Replacing x by x \cdot r, so that the integral boundaries become -1 and +1, we get  \pi r^3 \int_{-1}^1 (1-x^2) \,dx
The antiderivative needed can be determined very easily as    x-\frac{x^3}{3}
Thus, the sphere volume amounts to Vsphere =  \pi r^3 \cdot[1-1/3-(-1+1/3)]  =   \frac{4}{3}\pi r^3

This formula can be derived more quickly using the formula for the sphere surface area, which is r2. In Calculus, an antiderivative, primitive or indefinite integral of a function f is a function F whose Derivative Surface area is the measure of how much exposed Area an object has The volume of the sphere consists of layers of infinitesimal spherical slabs, and THE sphere volume is equal to

 \int_0^r 4\pi r^2 \,dr =   \frac{4}{3}\pi r^3

  3. The issues of a periodical over a period of one year. (I looked at this week's copy of the magazine. It was volume 23, issue 45.)
  4. A single book of a publication issued in multi-book format, such as an encyclopedia. (The letter "G" was found in volume 4.)
