Quizplus · Accepted Answer

Density is defined as mass per unit volume. Lead has a very high density, with a density of 11.34 grams per cubic centimeter. In comparison, snow has a density of approximately 0.1-0.5 grams per cubic centimeter, air has a density of approximately 0.0012 grams per cubic centimeter, textbooks have a density of approximately 0.6-1.5 grams per cubic centimeter, and feathers have a density of approximately 0.02-0.5 grams per cubic centimeter. Thus, the cubic meter of lead has the greatest density.
