[Solved] Liquid Density Puzzle
I think there's an assumption here that I'm missing, firstly I worked out how big each cube was by setting up simple simultaneous equations which gave me;
Green = 0.21m Red = 0.14m & Blue = 0.28m
And also Green + Red + Blue = 20kg. From here I'm stuck, I've thought about putting them all together giving me a volume of;
21^3 * 10^-6 + 14^3 * 10^-6 + 28^3 * 10-^6
=9261 +10^-6 + 2744 *10^-6 + 21952 * 10^-6
= 33957 * 10^-6 = 3.3957 * 10^-2 m³
Giving them all a density of 20 / that, but I'm sure it's a dead end =|, can anyone else see a better way of doing this?/An assumption that I'm missing?
thanks a lot in advance.
