The question, in short
Using mass 4810 g rounded to the nearest 10 g and density 7.7 g/cm³ rounded to 1 d.p., find the lower bound of the prism's volume.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 3 marks
- 1Lower bound of mass = 4810 − 5 = 4805 g
- 2Upper bound of density = 7.7 + 0.05 = 7.75 g/cm³
- 3Lower bound of volume = 4805 ÷ 7.75 = 620 cm³
