If the ratio of surface areas of 2 similar figures is 144/25 ; What is the ratio of their volumes?
kkurt [141]

Answer:

1728/ 125

Step-by-step explanation:

The ratio of corresponding lengths  of the figures = ratio of the square root of their areas.

So ratio of lengths =  12/5.

Now volume is 3 dimensional  so the ratio is the cube  of the lengths

= 12^3/5^3

= 1728/ 125.
