1. What is Density of Boulder Stone?

Definition: Density is the mass per unit volume of boulder stone, typically measured in kilograms per cubic meter (kg/m³).

Purpose: Knowing the density helps in estimating material requirements, structural calculations, and transportation planning.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of the boulder stone is divided by its volume to calculate its density.

3. Typical Density Values

Details: Boulder stone density typically ranges between 2200–2800 kg/m³ depending on the stone type:

• Granite: 2600-2800 kg/m³
• Basalt: 2400-2800 kg/m³
• Sandstone: 2200-2600 kg/m³
• Limestone: 2300-2700 kg/m³

4. Using the Calculator

Tips: Enter the mass of the boulder stone in kilograms and its volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is density important for boulder stones?
A: Density affects weight-bearing capacity, structural stability, and transportation requirements.

Q2: How do I measure the volume of irregular boulders?
A: Use water displacement method or laser scanning for accurate measurements of irregular shapes.

Q3: Does moisture affect boulder density?
A: Yes, wet stones will have higher density due to water absorption in pores.

Q4: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units (kg/m³).

Q5: How does density vary by stone type?
A: Igneous rocks like granite are denser than sedimentary rocks like sandstone.
