In mathematics, a cube root of a number x is a number y such that y3 = x. All nonzero real numbers have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted , is 2, because 23 = 8, while the other cube roots of 8 are and . The three cube roots of −27i are:
The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3 . The cube is also the number multiplied by its square : n3 = n × n2 = n × n × n. The cube function is the function x ↦ x3 (often denoted y = x3) that maps a number to its cube. It is an odd function, as.
1728 in 3. 1⁄27 yd 3. SI units. 0.02831685 m 3. The cubic foot (symbol ft or cu ft) [1] is an imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot ( 0.3048 m) in length. Its volume is 28.3168 L (about of a cubic metre ).
Click the image to see information page for details. In mathematics, a cubic plane curve is a plane algebraic curve C defined by a cubic equation. applied to homogeneous coordinates for the projective plane; or the inhomogeneous version for the affine space determined by setting z = 1 in such an equation. Here F is a non-zero linear combination ...
Algebraic form. Continued fraction. The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property. This number appears in the fractional expression for the golden ratio.
Harding turned to an even larger unclimbed face, the 2,900 feet (900 m) prow of El Capitan, at the other end of the valley. With Mark Powell and Bill "Dolt" Feuerer, they began the climb in July 1957. Rather than follow the single-push "alpine" style used on Half Dome, they were forced, given the technology of the day, to fix lines between "camps" in the style used in the Himalaya. Attempting ...
5.0292 m. The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units it is defined as feet, equal to exactly of a mile, or yards (a quarter of a surveyor's chain ), and is exactly 5.0292 meters. The rod is useful as a unit of length ...
The "Oriskany Sand", an important gas sand, has produced in excess of a trillion cubic feet of gas in West Virginia. Location: West Virginia Route 28 about 1.5 miles south of Springfield (missing) Hanging Rocks. Title: Hanging Rocks. Inscription: Perpendicular cliffs rising nearly 300 feet above the South Branch of the Potomac.
