1. Calculate the Volume:
* A cube's volume is side * side * side.
* Volume = 13 cm * 13 cm * 13 cm = 2197 cm³
2. Determine the Density:
* The density of strontium ferrite is typically around 4.8 g/cm³.
3. Calculate the Weight (Mass):
* Weight (mass) = Density * Volume
* Weight = 4.8 g/cm³ * 2197 cm³ = 10545.6 grams
Therefore, a 13 centimeter cube of strontium ferrite magnet would weigh approximately 10545.6 grams (or 10.5456 kg).
Important Note: The density of strontium ferrite can vary slightly depending on the manufacturing process and specific composition. This calculation is an estimate using a typical density value.
