What is the formula for calculating Bulk Density?

The formula for calculating Bulk Density is correctly represented by the option that involves subtracting the mass of the measure from the combined mass of the aggregate and the measure, and then dividing by the volume of the measure.

In this context, Bulk Density is calculated to determine the mass per unit volume of a material, which is essential in construction and material testing. The mass of the aggregate combined with the mass of the container (measure) gives the total mass, and subtracting the mass of the empty container accounts for the volume of just the aggregate. By dividing that net mass by the volume of the container, you derive the Bulk Density, which is crucial for understanding the weight and behavior of the aggregate in concrete mix designs.

This formula helps ensure accurate measurement and testing of aggregates used in concrete production, which subsequently affects the quality and stability of the concrete structures.
