Question

Each side of cube decresed by 25%. Find the ratio of the volumes of the original cube and the resulting cube
​

Answer 1

Answer:

let the length of the original cube is x

then volume is x^3

if the length decrease by 25%

then length is

x-x.25/100=3x/4

then volume is 27x^3/64

ratio of the volume of the original cube and resulting cube is

x^3:27x^3/64

=64:27
