What is the similarity ratio of two cubes with volumes of 64 cubic centimeters and 125 cubic centimeters?

2:3

4:5

1:5

16:25

Answer 1

my answr is b

Answer 2

if you know the volumes of two similar figures, you know that their lengths are similar. the ratio of their lengths is the cubed root of the ratio of their volumes

\[\sqrt[3]{\frac{64}{125}}\]

the cubed root of 64 is 4: 4*4*4= 16*4= 64
the cubed root of 125 is 5: 5*5*5= 25*5= 125
so the answer is
4/5
