What is the formula for density?

Correct option is D

The correct answer is (D) Density = Mass / Volume

Explanation:

• Density tells us how much mass is present in a given volume.
• Formula: Density = Mass ÷ Volume
• Units:
• In SI: kilogram per cubic metre (kg/m³)
• In CGS: gram per cubic centimetre (g/cm³)

Information Booster:

• If two objects occupy the same volume, the one with greater mass will have a higher density.
• Density helps to determine whether an object will float or sink in a fluid (based on Archimedes’ principle).
• Examples of densities:
• Water: 1000 kg/m³
• Iron: 7870 kg/m³
• Gold: 19300 kg/m³

Additional Knowledge:

• Option A (Volume ÷ Mass): This is the inverse of density.
• Option B (Mass × Volume): Incorrect; this is not a valid physical property.
• Option C (Weight ÷ Volume): This gives specific weight, not density.
