Mar 14, 2023 · In order to determine these densities, we might weigh a cubic centimeter of each type of glass. If the flint sample weighed 7.2 g and the bottle glass 2.4 g, we could describe the density of flint as 7.2 g cm –3 and that of bottle glass as 2.4 g cm –3. (Note that the negative exponent in the units cubic centimeters indicates a reciprocal.

Chert vs Flint (EXPLAINED) For about 2.5 million years, humans shaped stones into tools. In the stone age, early humans relied on their environment to survive, turning microcrystalline quartz into tools, such as shovels, hoes, and axes.
