  2. Prince Rupert's cube - Wikipedia

    en.wikipedia.org/wiki/Prince_Rupert's_cube

    Wallis assumed that the hole would be parallel to a space diagonal of the cube. The projection of the cube onto a plane perpendicular to this diagonal is a regular hexagon, and the best hole parallel to the diagonal can be found by drawing the largest possible square that can be inscribed into this hexagon. Calculating the size of this square ...

    One brass is exactly 100 square feet (9.29 m 2) area (used in measurement of work done or to be done, such as plastering, painting, etc.). The same word is used, however, for 100 cubic feet (2.83 m 3 ) of estimated or supplied loose material, such as sand, gravel, rubble, etc.

    The Harry Watts square drill bit is based on a Reuleaux triangle shape. It is used together with a guide and a particular chuck to make a square hole. [3] [4] Similarly, the company also manufactures drill bits for other angular holes such as pentagons and hexagons.

  5. Napkin ring problem - Wikipedia

    en.wikipedia.org/wiki/Napkin_ring_problem

    In geometry, the napkin-ring problem involves finding the volume of a "band" of specified height around a sphere, i.e. the part that remains after a hole in the shape of a circular cylinder is drilled through the center of the sphere.

  6. Genus (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Genus_(mathematics)

    In layman's terms, the genus is the number of "holes" an object has ("holes" interpreted in the sense of doughnut holes; a hollow sphere would be considered as having zero holes in this sense). [3] A torus has 1 such hole, while a sphere has 0. The green surface pictured above has 2 holes of the relevant sort. For instance:

  7. Inscribed square problem - Wikipedia

    en.wikipedia.org/wiki/Inscribed_square_problem

    The inscribed square problem, also known as the square peg problem or the Toeplitz' conjecture, is an unsolved question in geometry: Does every plane simple closed curve contain all four vertices of some square? This is true if the curve is convex or piecewise smooth and in other special cases. The problem was proposed by Otto Toeplitz in 1911. [1]

    67 million to one. That’s the odds of making two holes-in-one in a single round, according to the National Hole-In-One Registry. On Friday, Frank Bensel Jr. made two in a row.

  9. Square (unit) - Wikipedia

    en.wikipedia.org/wiki/Square_(unit)

    The square is an Imperial unit of area that is used in the construction industry in the United States and Canada, [1] and was historically used in Australia. One square is equal to 100 square feet . Examples where the unit is used are roofing shingles, metal roofing, vinyl siding, and fibercement siding products.
