Final answer:
The bulk density of the soil sample is calculated by dividing the mass (1550+E grams) by its volume (1000 cm³).
Step-by-step explanation:
The subject of the question concerns the calculation of bulk density of a soil sample, based on given dimensions and mass, as well as the consideration of the soil's water content represented by a percentage. To calculate the bulk density, we must divide the total mass of the soil sample by its volume. Given the dimensions of the soil sample (10cm x 10cm x 10cm), its volume is 1000 cm³. The stated problem includes a mass with an additional variable 'E', therefore, the mass is 1550+E grams. Bulk density (ρ) is hence calculated as follows: ρ = (1550+E g) / 1000 cm³. Since 1 g/cm³ is equivalent to 1000 kg/m³, this equation can also be expressed in terms of kg/m³ if needed.
The bulk density of a material is defined as its mass per unit volume. To calculate the bulk density of the given soil sample, we need to find the volume and mass of the sample.
The volume of the cubic soil sample is given by its dimensions: 10cm x 10cm x 10cm = 1000 cm³.
The mass of the soil sample is given as 1550+E g.
The bulk density is then calculated by dividing the mass by the volume: Bulk density = (1550+E g) / 1000 cm³.
Since the void ratio is given as 0.CD, which represents a decimal number, we can use the given values to find the bulk density in the correct units.
