  2. Gyroelongated square bipyramid - Wikipedia

    en.wikipedia.org/wiki/Gyroelongated_square_bipyramid

    The surface area of a gyroelongated square bipyramid is 16 times the area of an equilateral triangle, that is: [4], and the volume of a gyroelongated square bipyramid is obtained by slicing it into two equilateral square pyramids and one square antiprism, and then adding their volume: [4] + +.

  3. Gyroelongated square pyramid - Wikipedia

    en.wikipedia.org/wiki/Gyroelongated_square_pyramid

    The surface area of a gyroelongated square pyramid with edge length is: [3] (+), the area of twelve equilateral triangles and a square. Its volume: [ 3 ] 2 + 2 4 + 3 2 6 a 3 ≈ 1.193 a 3 , {\displaystyle {\frac {{\sqrt {2}}+2{\sqrt {4+3{\sqrt {2}}}}}{6}}a^{3}\approx 1.193a^{3},} can be obtained by slicing the square pyramid and the square ...

  4. Surface area - Wikipedia

    en.wikipedia.org/wiki/Surface_area

    A sphere of radius r has surface area 4πr 2.. The surface area (symbol A) of a solid object is a measure of the total area that the surface of the object occupies. [1] The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with ...

  5. Capped square antiprismatic molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Capped_square_anti...

    Square antiprisms can be capped on both square faces, giving bicapped square antiprismatic molecular geometry. The bicapped square antiprismatic atoms surrounding a central atom define the vertices of a gyroelongated square bipyramid. [2] The symmetry group of this object is D 4d. [3] Examples: B 10 H 12, defined by the B 10 framework

  6. Defining equation (physical chemistry) - Wikipedia

    en.wikipedia.org/wiki/Defining_equation...

    Theoretical chemistry requires quantities from core physics, such as time, volume, temperature, and pressure.But the highly quantitative nature of physical chemistry, in a more specialized way than core physics, uses molar amounts of substance rather than simply counting numbers; this leads to the specialized definitions in this article.

  7. Frustum - Wikipedia

    en.wikipedia.org/wiki/Frustum

    The Egyptians knew the correct formula for the volume of such a truncated square pyramid, but no proof of this equation is given in the Moscow papyrus. The volume of a conical or pyramidal frustum is the volume of the solid before slicing its "apex" off, minus the volume of this "apex":

  8. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. One example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist.

  9. Pyramid (geometry) - Wikipedia

    en.wikipedia.org/wiki/Pyramid_(geometry)

    The volume of a pyramid is the one-third product of the base's area and the height. The pyramid height is defined as the length of the line segment between the apex and its orthogonal projection on the base. Given that is the base's area and is the height of a pyramid, the volume of a pyramid is: [29] =.
