A metal block has a density of 2700 kg/m3 and a volume of 0.020 m3.
Use the equation: density=massvolume\text{density} = \dfrac{\text{mass}}{\text{volume}}density=volumemass
What is the mass of the block?

5.4 kg5.4\ \text{kg}5.4 kg
54 kg54\ \text{kg}54 kg
1.35×105 kg1.35 \times 10^{5}\ \text{kg}1.35×105 kg
