an object has a mass of 180 kg and a volume of 90 m3. what is its density?
Answer: The density of object is \(2kg/m^3\)
Explanation:
To calculate density of a substance, we use the equation:
\(\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}\)
We are given:
Mass of object = 180 kg
Volume of object = \(90m^3\)
Putting values in above equation, we get:
\(\text{Density of object}=\frac{180kg}{90m^3}\\\\\text{Density of object}=2kg/m^3\)
Hence, the density of object is \(2kg/m^3\)
