An empty swimming pool is filled to capacity in 60 minutes, by a hose that adds 3 cubic feet of water per minute. The square swimming pool is 12 feet wide. How deep is the water in the pool? (There are 12 inches per foot.)


How can you know that the swimming pool is square if neither the length is
given nor is the shape of the pool specified as a square. This seems like an
assumption to me, and I know that assumptions on the GMAT can be dangerous!
Am I missing something here? Any suggestions or insights? Thanks.

It seems like the problem specifically states that the swimming pool is in fact square and that each of its sides is of length 12. One of the most important aspects of scoring well on the gmat is to not permit your anxieties to undermine your ability to focus. You have to read the problem carefully, consider the data that is given, organize it in a way that it illuminates your understanding of what is being asked. Then you have to use these qualities to determine "what's the angle" in the problem before executing the solution process.

Cheers,
Steve
