### How do you find the density of chalk?

Density is measure as mass/volume. As with any matter, the
density of chalk would require:
1. a measurement of its mass
2. a measurement for its volume.
Mass can be measures on a scale in kg. Chalk's shape also makes
it calculable for volume (in metres). If it is cylindrical, measure
the height and the radius, then solve for V = (pi)(r^2)h. Divide
the mass by that volume and find its density in kg/m^3.
