Question 973766: A cubic cavity of edge 20 micrometer is filled with a fluid with a cubic solid of edge 2 micrometer. what percent of the cavity volume is occupied by the fluid? answer with explanation

The cube has volume 20*20*20=8000 micrometers^3
If I understand the problem, there is fluid put in with the equivalent of a cubic solid of 2*2*2, or 8 micrometer^3. That would be 8/8000, 1/1000th the volume or 0.1%.
One may also do it with ratios.
it is 1 cube /another cube.
The ratio of each side is 1 to 10 or 10%
Cubing that ratio makes the total volume ratio 1 to 1000, or 0.1%
