Most plastic is like 1.5 grams/cm^3; that's like 9 cubic centimeters, or less than 1/4 the volume of a golf ball.
When you're saying "about" and then cubing the number you can have a pretty significant difference.
- dyauspitr 2y agoAverage density of plastic is closer to 1.2g/cm3 which is what I was using.
- mlyle 2y agoYou'd only be off by a factor of 3 instead of 4, then. In any case, comparing it to a solid ball isn't so useful. Even the idea of "density" for something that is dispersed as small particles isn't too useful; proportion of mass is really the only useful metric.
