Question: If the mass of an object is measured in kilograms and its volume in cubic meters, what is the unit of density? (2022)

Options:

Correct Answer: kg/m^3

Exam Year: 2022

Solution:

Density is defined as mass per unit volume, so the unit of density is kg/m³.

If the mass of an object is measured in kilograms and its volume in cubic meters, what is the unit of density? (2022)

If the mass of an object is measured in kilograms and its volume in cubic meters, what is the unit of density? (2022)

Step 1: Understand that density is a measure of how much mass is in a certain volume.
Step 2: Identify the unit of mass, which is kilograms (kg).
Step 3: Identify the unit of volume, which is cubic meters (m³).
Step 4: To find the unit of density, combine the unit of mass with the unit of volume.
Step 5: Write the formula for density as mass divided by volume: Density = Mass / Volume.
Step 6: Substitute the units into the formula: Density = kg / m³.
Step 7: Simplify the expression to get the unit of density: kg/m³.

Density – Density is a physical property defined as mass divided by volume, typically expressed in units of mass per unit volume.
