Which object holds the least? The
wading pool, the cup, or the pan.
A good way to answer the question
is to think about how long it would take to fill each item with water. As we’re looking for the object
which holds the least, we’re looking for the object which will be the quickest to
fill with water.
It would take a long time to fill a
wading pool. You probably need a hose. We could fill a cup very quickly
using the tap. We could also fill a pan using a
tap. But it would take longer to fill
the pan than it would the cup. So the object which holds the least
is the cup.
