let the the radius be 5x and 8x
volume of 1st sphere is 4/3πr^3
4/3×π×(5x)^3
4/3×π×125x^3..
volume of 2nd sphere is 4/3×π×(8x)^3
4/3×π×256x^3
ratio= 4/3π×125x^3/ 4/3π×256x^3
= 125/256
so ratio 125:256
volume of 1st sphere is 4/3πr^3
4/3×π×(5x)^3
4/3×π×125x^3..
volume of 2nd sphere is 4/3×π×(8x)^3
4/3×π×256x^3
ratio= 4/3π×125x^3/ 4/3π×256x^3
= 125/256
so ratio 125:256
