3 <p>Cube root is defined as a value which when cubed gives the original number or it can be said as the value of “y” where Itself multiplied thrice (yxyxy) equals 343. Cube roots find their uses in a wide range in our everyday activities including engineering, measuring densities and volumes of different shapes or designing open spaces.</p>

4 <h2>What is the cube root of 343?</h2>

5 <p>We know that 343 is a<a>perfect cube</a>so the<a>cube root</a>of 343 is equal to 7. The cube root of 343 is written as ∛343, where the sign “∛” denotes the radical. </p>

6 <h2>Finding the Cube Root of 343</h2>

7 <p>We can find the<a>cube</a>root of 343, mainly through two methods: </p>

8 <p>i) Prime Factorization method.</p>

9 <p>ii) Subtraction method </p>

10 <h3>Cube Root of 343 By Prime Factorization</h3>

11 <p>To find a cube root of 343 the Prime Factorization method is one of the most widely and easiest methods to find the cube root of 343 that involves determining the<a>factor</a>of 343.</p>

12 <p><strong>Step 1 -</strong>Find the<a>prime factors</a>of 343. </p>

13 <p>So, the prime factors of 343 are 7×7×7</p>

14 <p><strong>Step 2 -</strong>The next thing you need to do is group the factors of 343 together in a group of 3(i.e.,<a>power</a>of 3).</p>

15 <p><strong>Step 3 -</strong> Here, we get the factor 7 in the power of 3, i.e., 73 or 7×7×7 </p>

16 <p>The cube root of 343 can be written as ∛343 = ∛7×7×7 = 7 </p>

17 <p>So through the above calculations, we can say that the cube root of 343 is 7.</p>

22 <p><strong>Step 1 -</strong>Subtract the 1st odd number : 343-1 = 342 </p>

21 <p><strong>Step 1 -</strong>Subtract the 1st odd number : 343-1 = 342 </p>

23 <p><strong>Step 2 -</strong>Subtract the next odd number: 342-7 = 335</p>

22 <p><strong>Step 2 -</strong>Subtract the next odd number: 342-7 = 335</p>

24 <p><strong>Step 3 -</strong>Subtract the next odd number: 335-19 = 316</p>

23 <p><strong>Step 3 -</strong>Subtract the next odd number: 335-19 = 316</p>

25 <p><strong>Step 4 -</strong>Subtract the next odd number: 316-37 = 279</p>

24 <p><strong>Step 4 -</strong>Subtract the next odd number: 316-37 = 279</p>

26 <p><strong>Step 5 -</strong>Subtract the next odd number: 279-61 = 218</p>

25 <p><strong>Step 5 -</strong>Subtract the next odd number: 279-61 = 218</p>

27 <p><strong>Step 6 -</strong>Subtract the next odd number: 218- 91 = 127</p>

26 <p><strong>Step 6 -</strong>Subtract the next odd number: 218- 91 = 127</p>

28 <p><strong>Step 7 -</strong>Subtract the next odd number: 127-127 = 00 </p>

27 <p><strong>Step 7 -</strong>Subtract the next odd number: 127-127 = 00 </p>

29 <p>Here, the<a>subtraction</a>took place seven times to reach zero.</p>
