The ratio of the surface areas of two similar solids is 4:49. What is the ratio of a volumes?
1 answer:
Answer: 8/343
Step-by-Step:
If two similar solids have a scale factor of a:b then,
The ratio of their surface areas (2D) is- a^2:b^2
The ratio of their volume (3D) is- a^3:b^3
First you want to square root the scale factor numbers to find the original value. Then you cube the original numbers to find the answer.
