Simpson's rules are used to calculate the volume of lifeboats, [6] and by surveyors to calculate the volume of sludge in a ship's oil tanks. For instance, in the latter, Simpson's 3rd rule is used to find the volume between two co-ordinates. To calculate the entire area / volume, Simpson's first rule is used. [7]
Archimedes also devised a way to calculate the volume of an irregular object, by submerging it underwater and measure the difference between the initial and final water volume. The water volume difference is the volume of the object.
In this case, the cross-sectional area becomes nearly the same as that of a sphere with equal volume. [6] In addition, the favored mean particle size for laser diffraction results is the D[4,3] or De Brouckere mean diameter , which is typically applied to measurement techniques where the measured signal is proportional to the volume of the ...
The surface-area-to-volume ratio has physical dimension inverse length (L −1) and is therefore expressed in units of inverse metre (m −1) or its prefixed unit multiples and submultiples. As an example, a cube with sides of length 1 cm will have a surface area of 6 cm 2 and a volume of 1 cm 3. The surface to volume ratio for this cube is thus
This irregular packing will generally have a density of about 64%. Recent research predicts analytically that it cannot exceed a density limit of 63.4% [ 9 ] This situation is unlike the case of one or two dimensions, where compressing a collection of 1-dimensional or 2-dimensional spheres (that is, line segments or circles) will yield a ...
An example of a spherical cap in blue (and another in red) In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane.It is also a spherical segment of one base, i.e., bounded by a single plane.
The volume of the auditorium is between 3 and 3.5 million cubic feet (between 85,000 and 99,000 cubic metres). [51] Melbourne Cricket Ground A common measure of volume in Australia, and in the state of Victoria in particular, is the Melbourne Cricket Ground, the largest stadium in Australia and 13th largest in the world.

One derivation replaces the integrand () by the quadratic polynomial (i.e. parabola) () that takes the same values as () at the end points and and the midpoint +, where = /.
