Question

plz tell me fast with the whole process each step by step​

Answer 1

Let the 3 numbers are ....

x,2x and 3x

now .....

$x {}^{3} + (2x) {}^{3} + (3x) {}^{3} \\ = x {}^{3} + 8x {}^{3} + 27x {}^{3} \\ = 36x {}^{3} \\ \\ according \: to \: the \: problem \\ 36x {}^{3} = 4500 \\ = > x = \sqrt[3]{ \frac{4500}{36} } \\ = > x = \sqrt[3]{125} = 5$

the numbers are ...5,10,15
