In the same question, you have pounds, liters, kilograms, and density. Can't you copy your question as it is written EXACTLY in your book or assignment??

how many liters of aluminum are obtained from the cans? (1 kg = 2.20 pounds) , (density of aluminum 2.70 kg/m^3)

3500 cans,

$$\frac{21 cans}{1.0 lbs}\qquad \frac{1kg}{2.2lbs}\qquad \frac{2.7kg}{m^3}\qquad \frac{1000L}{m^3}\qquad \qquad find\;\;L\\ \\~\\ \frac{1000L}{m^3}\times \frac{1m^3}{2.7kg}\times \frac{1kg}{2.2lbs} \times \frac{1.0 lbs}{21 cans}\times \frac{3500cans}{1}\\~\\ =\frac{1000*1*1*1*3500L}{1*2.7*2.2*21*1}\\ =\frac{1000*3500L}{2.7*2.2*21}\\ =\frac{50000000}{27*22*3}L\\ \approx 28\;058.4L$$
