this method is used to determine the field density of soil and bulk density of soil wrt to sand.
this method is not suitable for organic , saturated. highly plastic soil that will deform during the excavation of soil.
The in-situ density of the soil is required to control the results of field compaction in earth embankments, Road fill and structural back filling. So, measuring the soil density is essential before building any construction. Three methods are used to determine the density (unit weight) of a soil in the sight; the sand replacement method, the balloon method, and the nuclear method.
Seismic reflection is the method that uses the density differences of rocks to interpret subsurface structures. It involves sending seismic waves into the ground and measuring the reflections to create a picture of the subsurface geology based on the different densities of rock layers.
The compacted density of quarry dust can vary depending on factors such as particle size, moisture content, and compaction method. On average, the compacted density of quarry dust is typically around 1500-2000 kg/m^3. It is recommended to conduct site-specific testing to determine the exact compacted density for a specific application.
To find out the density of a pebble, you will need a balance or scale to measure its mass, and a graduated cylinder filled with water to measure its volume using water displacement method. The density of the pebble can then be calculated by dividing its mass by its volume.
Bronze casting is a method in which molten bronze is poured into a mold to create a three-dimensional object. The bronze in this process replaces the material that fills the mold, ultimately forming the desired shape once it solidifies.
sand replacement method is used for determining the dry density of soil
Core cutter method is simple but results approximate and used on soft soils
In finding the density of a rectangular solid object, you can simply calculate it by dividing the mass by the volume using the formula density = mass/volume. However, for an irregular solid object, you may need to use techniques like displacement method or water displacement method to determine its volume before calculating the density.
Experiments are a method for finding solutions to problems.
The determination of density by the slope method is generally more accurate because it involves finding the slope of a linear relationship between mass and volume, which reduces the effect of random errors in individual data points. This method is based on multiple data points and takes into account the overall trend in the data, leading to a more precise calculation of density.

Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
