Final answer:
Density is calculated as mass divided by volume. For a cube with a mass of 100g and a volume of 50cm^3, the density is 2g/cm^3. Different materials have different densities, ranging widely as indicated in Table 3.1 of the book.
Step-by-step explanation:
The student has asked about calculating the density of a cube. Density is defined as the mass of an object divided by its volume. In the context of the problem provided, the mass of the cube is 100g, and the volume is 50cm3. Therefore, the density can be calculated by using the formula:
Density = Mass / Volume
Plugging the given values into this formula, we get:
Density = 100g / 50cm3 = 2g/cm3
This value is an indication of how much mass is contained in a certain volume of the cube. The units used for density here are grams per cubic centimeter (g/cm3), which are common units for this type of measurement.
Materials may vary widely in density, which can be seen in Table 3.1 of the referenced book, showing densities of different materials, ranging from very light materials like plastic foam (less than 0.1 g/cm3) to very dense materials like gold (19.3 g/cm3). This concept is important not only in physics but also in various scientific fields like chemistry and engineering.
