Water drips from a faucet into a flask at the rate of two drops every 2 seconds. A cubic centimeter (cm3) contains 20 drops. What volume of water, in cubic decimeters (dm3), will be collected in 3 hours?
3600 seconds in one hour
10800 seconds in three hours therefore there are 10800 drops in three hours
10800/20 drops =540 cm3
There are .001 dm3 in a cm3
540 cm3 x .001 = .54 dm3
0.54 dm3 is correct.
