Explanation:

To determine the density of earth - materials, first use a triple beam balance to measure the mass of the sample in grams. For regular - shaped samples, a ruler can be used to measure dimensions and calculate the volume in $cm^3$. For irregular - shaped samples, a graduated cylinder is used to find the volume by the displacement method. Density is calculated using the formula $
ho=\frac{M}{V}$, where $
ho$ is density in $g/cm^3$, $M$ is mass, and $V$ is volume.

Answer:

To determine the density of earth materials, start by measuring the mass of the sample. Place the sample on a triple beam balance and record its mass in grams. If the sample has a regular shape, use a ruler to measure its dimensions (length, width, height) and calculate the volume in $cm^3$ using the appropriate geometric formula. For example, for a cube, $V = l\times w\times h$. If the sample is irregularly shaped, use a graduated cylinder. First, fill the graduated cylinder with a known volume of water, record this volume ($V_1$). Then, carefully place the sample into the water, making sure it is fully submerged. Record the new volume of the water - sample combination ($V_2$). The volume of the sample is $V = V_2 - V_1$. Once the mass ($M$) and volume ($V$) are known, calculate the density using the formula $
ho=\frac{M}{V}$, where the density $
ho$ is expressed in $g/cm^3$. This procedure allows for an accurate determination of the density of earth materials.
