  2. Lake Erie - Wikipedia

    en.wikipedia.org/wiki/Lake_Erie

    Lake Erie has a lake retention time of 2.6 years, [24] the shortest of all the Great Lakes. [25] The lake's surface area is 9,910 square miles (25,667 km 2). [7] [26] Lake Erie's water level fluctuates with the seasons as in the other Great Lakes. Generally, the lowest levels are in January and February and the highest in June or July, although ...

    The following is a list of the 100 largest lakes of the United States by normal surface area. The top twenty lakes in size are as listed by the National Atlas of the United States, a publication of the United States Department of the Interior. The area given is the normal or average area of the lake. The area of some lakes fluctuates substantially.

  5. Augmented triangular prism - Wikipedia

    en.wikipedia.org/wiki/Augmented_triangular_prism

    An augmented triangular prism with edge length has a surface area, calculated by adding six equilateral triangles and two squares' area: [2] +. Its volume can be obtained by slicing it into a regular triangular prism and an equilateral square pyramid, and adding their volume subsequently: [ 2 ] 2 2 + 3 3 12 a 3 ≈ 0.669 a 3 . {\displaystyle ...

    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 ] 2 2 + 3 4 a 3 ≈ 1.140 a 3 , {\displaystyle {\frac {2{\sqrt {2}}+{\sqrt {3}}}{4}}a^{3}\approx 1.140a^{3},} can be derived by slicing it into a central prism and three square pyramids, and adding their volumes.

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

    The surface area of a right prism is: +, where B is the area of the base, h the height, and P the base perimeter. The surface area of a right prism whose base is a regular n-sided polygon with side length s, and with height h, is therefore: = ⁡ +.

  9. Triangular prism - Wikipedia

    en.wikipedia.org/wiki/Triangular_prism

    In geometry, a triangular prism or trigonal prism [1] is a prism with 2 triangular bases. If the edges pair with each triangle's vertex and if they are perpendicular to the base, it is a right triangular prism. A right triangular prism may be both semiregular and uniform. The triangular prism can be used in constructing another polyhedron.
