CAIE IGCSE Physics Density as Mass per Unit Volume

Practise defining density and rearranging ρ = m/V for density, mass or volume across solids, liquids and gases, with careful geometry and unit conversion.

Syllabus
2026–2028
Course
Physics 0625

Exam points

  • choose ρ = m/V and rearrange it for mass or volume before substituting the measured values
  • calculate cuboid, cylinder or sphere volume and keep mass-volume units compatible
  • interpret density comparisons or changes when volume changes while mass remains constant

1.4.1—Density as mass per unit volume question 1

[Maximum number: 2]

All the sides of a plastic cube are 8.0 cm long. Fig. 3.1 shows the cube.
