A cube is a three-dimensional geometric shape with six equal square faces. In mathematics, the term "cube" also refers to the result of raising a number to the third power. The symbol for cubing a number is ³.
For example, if we take the number 3 and cube it:
3³ = 3 × 3 × 3 = 27
Thus, the cube of 3 is 27.
The cube root of a number is a value that, when multiplied by itself three times, gives the original number. The symbol for cube root is ∛.
For example, to find the cube root of 27:
∛27 = 3
This means that 3 is the cube root of 27, because:
3 × 3 × 3 = 27
4³ = 4 × 4 × 4 = 64
∛64 = 4
(−2)³ = (−2) × (−2) × (−2) = -8
∛(-8) = -2
A cube calculator and a cube root calculator are essential tools for solving mathematical problems involving cubes and roots. These calculators simplify complex calculations and provide accurate results efficiently.

8
Therefore, the value of the cube of 2 is, 2³ = 8. To compute the cube of a number like 2, simply multiply it by itself three times. For example, 2 × 2 × 2 = 8.
1 to 27,000
The cubes of numbers from 1 to 30 range from 1³ = 1 to 30³ = 27,000. Calculating the cube of numbers within this range involves raising each number to the power of three.
1 to 8,000
The cubes of numbers from 1 to 20 range from 1³ = 1 to 20³ = 8,000. To find the cube of any number within this range, multiply the number by itself twice more.
Formula: (n(n + 1) / 2)²
The sum of the cubes of the first n natural numbers can be calculated using the formula (n(n + 1) / 2)². For example, the sum of the cubes of the first 3 natural numbers (1, 2, 3) is (3 × 4 / 2)² = 36.
1 to 125,000
The cubes of numbers from 1 to 50 range from 1³ = 1 to 50³ = 125,000. To calculate the cube of any number in this range, multiply the number by itself twice more.
1, -0.5 + 0.8660i, -0.5 - 0.8660i
The cube roots of unity are the solutions to the equation x³ = 1. They include 1, -0.5 + 0.8660i, and -0.5 - 0.8660i. These roots are used in complex number theory and are crucial in various mathematical applications.
1 to 4.64
The cube roots of numbers from 1 to 100 range from 1³ = 1 to 100³ = 4.64. For instance, the cube root of 27 is 3, because 3³ = 27. Cube roots of numbers within this range can be found using a calculator or cube root tables.
A cube root function is a mathematical function that expresses the cube root of a number. It is written as f(x) = ∛x, where ∛ represents the cube root symbol. This function determines the value that, when multiplied by itself three times, yields the original number.
The graph of a cube root function has a characteristic S-shape. It passes through the origin (0,0) and extends into all four quadrants. The curve rises to the right and falls to the left, reflecting the fact that both positive and negative numbers have real cube roots. The general shape is smooth and continuous.
The cube root symbol is represented as ∛. It indicates that you are taking the cube root of the number that follows it. For example, ∛8 equals 2, since 2 × 2 × 2 = 8.
The cube root function is used in various fields such as engineering, physics, and finance. For instance, it helps calculate the dimensions of a cube when the volume is known, and it appears in formulas involving three-dimensional shapes.
Some key properties of cube root functions include:
