  2. Augmented triangular prism - Wikipedia

    en.wikipedia.org/wiki/Augmented_triangular_prism

    The augmented triangular prism can be constructed from a triangular prism by attaching an equilateral square pyramid to one of its square faces, a process known as augmentation. [1] This square pyramid covers the square face of the prism, so the resulting polyhedron has 6 equilateral triangles and 2 squares as its faces. [2]

  3. Triaugmented triangular prism - Wikipedia

    en.wikipedia.org/wiki/Triaugmented_triangular_prism

    A triaugmented triangular prism with edge length has surface area [10], the area of 14 equilateral triangles. Its volume, [10] +, can be derived by slicing it into a central prism and three square pyramids, and adding their volumes.

  4. Elongated square bipyramid - Wikipedia

    en.wikipedia.org/wiki/Elongated_square_bipyramid

    The square pyramid caps have shortened isosceles triangle faces, with six of these pyramids meeting together to form a cube. The dual of this honeycomb is composed of two kinds of octahedra (regular octahedra and triangular antiprisms), formed by superimposing octahedra into the cuboctahedra of the rectified cubic honeycomb .

  5. 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] + +.

  6. 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 ...

    If the area of the Square is 434 units. The area of the circle is 433.7. The ostracon depicting this diagram was found near the Step Pyramid of Saqqara. A curve is divided into five sections and the height of the curve is given in cubits, palms, and digits in each of the sections. [3] [4] At some point, lengths were standardized by cubit rods ...

  8. Square pyramid - Wikipedia

    en.wikipedia.org/wiki/Square_pyramid

    A polyhedron's surface area is the sum of the areas of its faces. The surface area of a right square pyramid can be expressed as = +, where and are the areas of one of its triangles and its base, respectively. The area of a triangle is half of the product of its base and side, with the area of a square being the length of the side squared.

  9. Biaugmented pentagonal prism - Wikipedia

    en.wikipedia.org/wiki/Biaugmented_pentagonal_prism

    the dihedral angle of an augmented pentagonal prism between pentagon-to-triangle is ⁡ +, for which adding the dihedral angle of an equilateral square pyramid between its base and its lateral face ⁡ (), and the dihedral angle of a regular pentagonal prism between its base and its lateral face.
