Answer 2

The numbers are 13, 26 , 39

Step-by-step explanation:

Three numbers are in ratio of 1:2:3

Let the ratio be x

So, Numbers are x , 2x and 3x

We are given that the sum of their cubes is 79092

So, $x^3+(2x)^3+(3x)^3=79092$

$x^3+8x^3+27x^3=79092$

$36x^3=79092$

$x=\sqrt[3]{\frac{79092}{36}}$

x=13

Number are :

x=13

2x=13(2)=26

3x=3(13)=39

Hence The numbers are 13, 26 , 39
