Final answer:
The density of the steel ball is calculated using the formula density = mass / volume, which gives a density of 7.8125 kg/m³ for the steel ball with a mass of 0.025 kg and volume of 0.0032 m³.
Step-by-step explanation:
To calculate the density of the steel ball given by your teacher, use the density formula:
Density = mass / volume
Here, the mass of the steel ball is 0.025 kg, and the volume is 0.0032 m³. Substituting these values into the formula gives:
Density = 0.025 kg / 0.0032 m³ = 7.8125 kg/m³
Thus, the density of the steel is 7.8125 kg/m³.
