GCSE Maths Practice: density-mass-volume

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

Select all correct options:

\( \text{315 g, 45 cm}^3 \Rightarrow \text{7 g/cm}^3 \) \( \text{240 g, 80 cm}^3 \Rightarrow \text{3 g/cm}^3 \) \( \text{300 g, 60 cm}^3 \Rightarrow \text{5.5 g/cm}^3 \) \( \text{420 g, 70 cm}^3 \Rightarrow \text{6 g/cm}^3 \)
