GCSE Maths Practice: units-and-conversions

Question 6 of 10

This question checks understanding of the density formula. Density relates mass and volume.

‹ ›

\( \begin{array}{l}\text{Which formula gives density?}\end{array} \)

Choose one option:

Always divide mass by volume to find density.

Density is mass divided by volume. To calculate it, take the mass of an object and divide by its volume. For instance, if mass = 600 g and volume = 200 cm³, density = 600 ÷ 200 = 3 g/cm³. Density explains why some objects float and others sink, and is key in material science, engineering, and physics. Practice with different units, and always ensure consistent units for correct results.
