A trash compactor can reduce the volume of its contents to 0.350 their original value. Neglecting the mass of air expelled, by what factor is the density of the rubbish increased?

Step-by-step solution Step 1 of 3 Formula to find the density of a substance is, …… (1) Here, is density, is mass and is volume of the substance. Step 2 of 3 At constant mass the density of substance is inversely proportional to its volume. Hence,
