Density Formula Manipulation: Find Mass or Volume (IGCSE Physics & Chemistry)

Описание: Master the key skill of rearranging the density formula to find mass or volume for your IGCSE Physics and Chemistry exams! In this advanced tutorial, we go beyond just 𝜌=m/V and teach you two powerful methods—the cross-multiplication proportion method and the magic triangle method—to easily solve for any unknown.

You'll see step-by-step examples ranging from simple calculations to complex problems where you must first calculate the volume of a cuboid, cylinder, cone, or sphere using its dimensions.

In this lesson, you’ll learn:
✅ Two foolproof methods to rearrange the density formula: Cross-Multiplication and the Magic Triangle.
✅ How to solve for mass (m) when you know density and volume.
✅ How to solve for volume (V) when you know density and mass.
✅ How to tackle multi-step problems where you must calculate the volume of a 3D shape first.

📚 Perfect for: IGCSE & GCSE Physics & Chemistry students, anyone preparing for exams that require formula manipulation, and students who want to build confidence in solving for unknowns.
