A block has a mass of 540 g and a volume of 200 cm³. What is its density?
Answer and explanation
Correct answer: D. 2.7 g/cm³
- Step 1: Density = mass ÷ volume.
- Step 2: 540 ÷ 200 = 2.7 g/cm³.
Answer
2.7 g/cm³.
Why not the others: 0.37 g/cm³: the volume was divided by the mass. 340 g/cm³: the values were subtracted. 108 000 g/cm³: the values were multiplied.
