Question

Three number are in the ratio 2:3 :5.the sum of their cubes is 34560.find the numbers.

Answer 1

Step-by-step explanation:

let 2x ,3x and 5x be the three numbers

(2x)^3+(3x)^3+(5x)^3= 34560

8x^3+27x^3+125x^3=34560

160x^3=34560

x^3=34560/160= 216

x=216⅓ (cube root. sorry can't text cube root. I have only this √)

=6

now, 2x=2*6= 12

3x= 3*6=18

5x= 5*6= 30

hope this help
