If the ratio of surface areas of 2 similar figures is 144/25 ; What is the ratio of their volumes?
Please explain how to solve this also :)

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.

The answer to this problem is A and here’s why:

If you look at the bottom part of the graph, which is the x-axis, you can see that it only goes up to 10 minutes, so that automatically eliminates choices B and C, and we can see that at 9 minutes, the y-axis of that line is at 80 meters, so that means that A is the answer.
