The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
The ratio is 19/9.
The ratio is sqrt(36) : sqrt(225) which is 6 : 15 or 2 : 5
The similarity ratio is 1:4.
If the ratio of similarity is 310, then the ratio of their area is 96100.
Measure any two corresponding edges. The ratio of these edges is the similarity ratio.

Volumes are cubic measures so the similarity ratio is cuberoot(343)/cuberoot(1331) = 7/11

Reduce it if possible. Then set it equal to the similarity ratio of a-cubed over b-cubed, take the cubed route and theres your answer.
You call it similarity.
482/1282 = 241/641.
