Hey ! there
Answer:
- n is equal to <u>3 </u><u>meters</u>
Step-by-step explanation:
In this question we are provided with a cube having <u>volume </u><u>2</u><u>7</u><u> </u><u>cubic </u><u>meters</u><u> </u>. And we are asked to find the <u>value </u><u>of </u><u>n </u>that is basically its <u>edge </u><u>.</u>
For finding the value of n we need to know the volume of cube. So ,

<u>Where</u><u> </u><u>,</u>
- a refers to <u>edge </u><u>of </u><u>cube</u>
<u>SOLUTION</u><u> </u><u>:</u><u> </u><u>-</u>
Substituting given volume that is 27 m³ and value of a as n in formula :

Applying cube root on both sides :
![\quad \longrightarrow \qquad \: \sqrt[3]{n {}^{3} } = \sqrt[3]{27}](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%5Cqquad%20%5C%3A%20%20%5Csqrt%5B3%5D%7Bn%20%7B%7D%5E%7B3%7D%20%7D%20%20%3D%20%20%5Csqrt%5B3%5D%7B27%7D%20)
We get ,
![\quad \longrightarrow \qquad \:n= \sqrt[3]{27}](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%5Cqquad%20%5C%3An%3D%20%20%5Csqrt%5B3%5D%7B27%7D%20)
We know that 3 × 3 × 3 is equal to 27 that means cube root of 27 is 3 . So ,

- <u>Henceforth</u><u> </u><u>,</u><u> </u><u>value</u><u> </u><u>of </u><u>n </u><u>is </u><u>❝</u><u> </u><u>3 </u><u>meters </u><u>❞</u>
<u>Verifying</u><u> </u><u>:</u><u> </u><u>-</u>
Now we are checking our answer whether it is wrong or right by substituting value of n and equating it with given volume that is 27 cubic meters . So ,
- a³ = 27 ( where a is equal to n )
Substituting values :
<u>Therefore,</u><u> </u><u>our</u><u> answer</u><u> is</u><u> correct</u><u> </u><u>.</u>
