Question

What is the cube of 20?

Answer 1

Hint: The cube of number 20 is its third power, that is, the result of multiplying three instances of the number 20 together. Cube of any number \[x={{x}^{3}}\].

Complete step-by-step answer:
Square root is when we multiply the lowest digit two times to arrive at the number. On the other hand, a cube root is when we multiply the lowest number three times to arrive at the number. A perfect cube refers to the integer or a whole number as the cube root.
First step will be multiplying the number 20 three times.
The cube of 20 is obtained.
The cube can be obtained as,
\[\begin{align}
  & cube\text{ }of\text{ }20={{20}^{3}} \\
 & cube\text{ }of\text{ }20=20\cdot 20\cdot 20 \\
 & cube\text{ }of\text{ }20=8000 \\
\end{align}\]
Thus, \[cube\text{ }of\text{ }20=8000\].

Note: The cube of number 20 is its third power, that is, the result of multiplying three instances of the number 20 together. The cube of a number or any other mathematical expression is denoted by a superscript 3 that is, Cube of \[x={{x}^{3}}\].
