Water drips from a faucet into a flask at the rate of two drops every 6 seconds. A cubic centimeter (cm3) contains 20 drops. What volume of water, in cubic decimeters (dm3), will be collected in 1 hour?

Answer 1

(2 drops/6 sec)*(1 cm^3/20 drops)*(3600s/h)= 60 cm^3/hour

Now convert cm^3 to dm^3. There are 1000 cm^3 in a dm^3 (liter)
