In other words, if the cube root of a number is an integer, then the number can be considered as a perfect cube.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">If x is a perfect cube of y, then we represent it as $x = y^{3}$.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Thus, in other words, the cube root of x is y.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">We write it as $^{3}\\sqrt{x}= y$.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">We write <strong>\u201cn cubed\u201d as <\/strong>$n^{3}$.<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Perfect cube examples:<\/strong> $1^{3} = 1, 2^{3} = 8, 3^{3} = 27, 5^{3} = 125,$ etc.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Note that we can find a cube of any number, whether it is an integer or a decimal, or a fraction.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">For example, the cube of 0.2 is given by<\/p>\n\n\n\n<p class=\"eplus-wrapper\">$0.2 \\times 0.2 \\times 0.2=0.008$<\/p>\n\n\n\n<div id=\"recommended-games-container-id\"

that the number is \u201ccubed.\u201d To find the cube root of a number, we need to reverse the process of cubing a number. For example:<\/p>\n\n\n\n<p class=\"eplus-wrapper\">When the number 3 is cubed, we get $3 \\times 3 \\times 3$, which is 27. The cube root of 27 is 3. This is because we get 27 on multiplying the number 3 three times. The <strong>symbol for cube root is <\/strong>$^{3}\\sqrt{}$<strong>.&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper\">If we want to express this in exponent form, we write it as:&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Cube root of a number $= (number)^{\\frac{1}{3}}$.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"424\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/cube-root-of-x-symbol.png\" alt=\"Cube root of x symbol\" class=\"wp-image-41500\" title=\"Cube root of x symbol\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/cube-root-of-x-symbol.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/cube-root-of-x-symbol-300x205.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading eplus-wrapper\" id=\"4-how-to-find-a-perfect-cube\">How to Find a Perfect Cube<\/h2>\n\n\n\n<p class=\"eplus-wrapper\">Every composite number can be expressed as the product of the power of its prime factors. If the power of all the prime factors is in the multiple of 3, then the number is known as a perfect cube. Each prime factor of a number appears three times in the prime factorization of its cube.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Step 1:<\/strong> Find the prime factorization of the given number.<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Step 2:<\/strong> Club all the same factors together.<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Step 3:<\/strong> Repeat the above step for all the sets of the group of the same three factors. If some factors are left behind, then we conclude that the given number is not a perfect cube. Otherwise, the given number is a perfect cube.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Let us take the following example to understand this.<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Example 1:<\/strong> Check if 2197 is a perfect cube number?<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Let us first find the prime factorization of 2197.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">$2197 = 13 \\times 13 \\times 13 = 13^{3}$<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Hence, 2197 is a perfect cube of 13.<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Example 2: Is 216 a perfect cube?<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"314\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/prime-factorization-of-216-using-division-method.png\" alt=\"Prime factorization of 216 using division method\" class=\"wp-image-41501\" title=\"Prime factorization of 216 using division method\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/prime-factorization-of-216-using-division-method.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/prime-factorization-of-216-using-division-method-300x152.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper\">$216 = (2 \\times2 \\times 2) \\times (3 \\times 3 \\times 3) = 2^{3} \\times 3^{3} = 6^{3}$<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Thus, 216 is a perfect cube.<\/p>\n\n\n\n<h2 class=\"wp-block-heading eplus-wrapper\" id=\"5-perfect-cube-formula\">Perfect Cube Formula<\/h2>\n\n\n\n<p class=\"eplus-wrapper\">To identify a perfect cube, we use the perfect cube formula.
