About This Quiz

In geometry, a polyhedron (plural polyhedra or polyhedrons) is a solid in three dimension with flat polygonal faces, straight edges and sharp corners or vertices. The word polyhedron comes from the Classical Greek πολύεδρον, as poly- (stem of πολύς, "many") + -hedron(form of ἕδρα, "base" or "seat").

    Cubical gaming dice in ..... have been dated back as early as 600 B.C. - ProProfs

    Cubical gaming dice in ..... have been dated back as early as 600 B.C.

    • China

    • Austria

    • Japan

    • England

    Correct Answer
    A. China
    Explanation
    Cubical gaming dice have been dated back as early as 600 B.C. in China. This suggests that gaming with dice was prevalent in ancient Chinese culture. The discovery of these dice provides evidence of the early origins of gaming and the use of dice as a form of entertainment in China.

    The topological class of a polyhedron is defined by its ..... characteristic and orientability. - ProProfs

    The topological class of a polyhedron is defined by its ..... characteristic and orientability.

    • Euler

    • Knuth

    • Leibniz

    • Newton

    Correct Answer
    A. Euler
    Explanation
    The topological class of a polyhedron is defined by its Euler characteristic and orientability. The Euler characteristic is a fundamental concept in topology that relates the number of vertices, edges, and faces of a polyhedron. It is given by the formula V - E + F = 2, where V is the number of vertices, E is the number of edges, and F is the number of faces. The orientability of a polyhedron refers to whether it has two distinct sides or not. Therefore, the correct answer is Euler.

    The earliest known written records of these shapes come from ....... authors.

    • Classical Greek

    • Modern English

    • Renaissance English

    • Medieval English

    Correct Answer
    A. Classical Greek
    Explanation
    The correct answer is Classical Greek because it is stated that the earliest known written records of these shapes come from Classical Greek authors. This suggests that the shapes were first documented and described by authors from the Classical Greek period.

    By 236 AD, who was describing the dissection of the cube into its characteristic tetrahedron (orthoscheme) and related solids, using assemblages of these solids as the basis for calculating volumes of earth to be moved during engineering excavations? - ProProfs

    By 236 AD, who was describing the dissection of the cube into its characteristic tetrahedron (orthoscheme) and related solids, using assemblages of these solids as the basis for calculating volumes of earth to be moved during engineering excavations?

    • Reinhold Hoppe

    • Bob Lee

    • Isaac Newton

    • Liu Hui

    Correct Answer
    A. Liu Hui
    Explanation
    Liu Hui is the correct answer because he was describing the dissection of the cube into its characteristic tetrahedron and related solids. He used these assemblages of solids to calculate volumes of earth to be moved during engineering excavations. This suggests that Liu Hui had knowledge and expertise in geometry and engineering calculations during that time period.

    In geometry, polyhedra  is a topic under? - ProProfs

    In geometry, polyhedra  is a topic under?

    • Discrete geometry

    • Toric geometry

    • Digital geometry

    • Convex geometry

    Correct Answer
    A. Discrete geometry
    Explanation
    Discrete geometry is the correct answer because polyhedra are a fundamental concept in this branch of geometry. Discrete geometry deals with the study of geometric objects that are discrete or countable, such as points, lines, and polygons. Polyhedra, which are three-dimensional geometric figures with flat faces and straight edges, are a key focus in discrete geometry. Therefore, polyhedra are a topic under discrete geometry.

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 3
    Explanation
    The question is asking for the number of generalizations of polyhedra. The correct answer is 3, which means that there are three generalizations of polyhedra.

    • 400 B.C

    • 250 B.C

    Correct Answer
    A. 600 B.C
    Explanation
    The correct answer is 600 B.C. This suggests that cubical gaming dice in China have been in existence since at least 600 B.C.

    By ...., Liu Hui was describing the dissection of the cube into its characteristic tetrahedron (orthoscheme) and related solids, using assemblages of these solids as the basis for calculating volumes of earth to be moved during engineering excavations.

    • 236 A.D

    • 245 A.D

    • 352 A.D

    • 200 A.D

    Correct Answer
    A. 236 A.D
    Explanation
    Liu Hui's description of the dissection of the cube into its characteristic tetrahedron and related solids suggests that he was using these assemblages of solids to calculate volumes of earth to be moved during engineering excavations. This indicates that Liu Hui was likely involved in engineering and construction projects during his time. The given answer of 236 A.D. suggests that Liu Hui was active and making these calculations during this time period.
