GCSE Maths Practice: density-mass-volume

\( \begin{array}{l} \text{Which of these correctly calculate mass?} \\ \text{(Use mass = density × volume)} \end{array} \)

Select all correct options:

\( \text{6.5 g/cm}^3,\ 20 cm^3 \Rightarrow \text{130 g} \) \( \text{3.2 g/cm}^3,\ 15 cm^3 \Rightarrow \text{48 g} \) \( \text{4.5 g/cm}^3,\ 30 cm^3 \Rightarrow \text{135 g} \) \( \text{2.5 g/cm}^3,\ 25 cm^3 \Rightarrow \text{70 g} \)
