Final answer:
To find the density of a regular solid, divide its mass by its volume. For example, if a cube has an edge length of 5 cm and a mass of 50 g, its density would be 0.4 g/cm³.
Step-by-step explanation:
The density of a regular solid can be found by dividing its mass by its volume.
For example, let's say we have a cube with an edge length of 5 cm and a mass of 50 g.
To find the volume, we cube the edge length: 5 cm * 5 cm * 5 cm = 125 cm³.
Next, we divide the mass (50 g) by the volume (125 cm³): 50 g / 125 cm³ = 0.4 g/cm³.
So, the density of the cube is 0.4 g/cm³.
