In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. 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.

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 × ...

Cubed. When a value is followed by the term "cubed," it means that the value is being raised to the power of three. For example, three cubed is written as follows: In the above figure, "cubed" refers to the exponent, 3. Cubing a value (raising it to the power of 3) just means to multiply the number by itself two times: 3 3 = 3 × 3 × 3 = 27.
Sep 24, 2020 · The “Cube” or “Exponent 3” or “Power of 3” of a number is the number multiplied by itself 3 times. It is written as number 3. Saying “4 cubed” or “4 to the power of 3” or “4 3 ” is the same as saying 4 x 4 x 4 = 64. Saying “10 cubed” or “10 to the exponent 3” or “10 3 ” is the same as saying 10 x 10 x 10 = 1,000.

May 30, 2024 · Cubed. A number taken to the power 3 is said to be cubed, so is called " cubed." This terminology derives from the fact that the volume of a cube of edge length is given by , hence the operation taking a cube's edge length to its volume is known as "cubing" and the quantity derived from by cubing is known as " cubed."
