Any number n with an exponent of 3 is written as n³. You pronounce it as "n cubed," or "nto the third power." To get the cube of a number multiply it by itself 3 times. Therefore the cube formula is n³ = n × n × n.
A perfect cube results when you cube an integer, or a whole number without decimals or fractions. For example, 3 cubed is written as 3³ and 3³ = 3 × 3 × 3 = 27. Since 3 is an integer, 27 is a perfect cube. Imagine a block of smaller cubes 3 high, 3 wide, and 3 deep resembling a Rubik's Cube puzzle. Basically it's 3 sets of 9 blocks arranged in a 3 ...
When you cube a negative number the result will always be a negative number. But it is important to understand how using parentheses affects the intepretation of the operation. Putting a negative sign before the number or outside of parentheses means "take the negative of the number, cubed" as in 1. -2³ means -(2 × 2 × 2) = -8 2. -(2)³ means -(2 × ...
In mathematics, a cube of a number means the result of multiplying the number by its square. For example, the cube of 6 is 6×6×6 = 216. It is named this because cubing a number gives the volume of a cube . Cubing a number can also be written as 6 3 = 36.
Cube, in Euclidean geometry, a regular solid with six square faces; that is, a regular hexahedron. Since the volume of a cube is expressed, in terms of an edge e, as e3, in arithmetic and algebra the third power of a quantity is called the cube of that quantity.
