An empty swimming pool is to be filled to the top. The pool is shaped like a rectangular prism with length 16m, width 10m, and depth 5m. Suppose water is pumped into the pool at a rate of 40m3 per hour. How many hours does it take to fill the empty pool?
Answers: 3
. Using Dimensional Analysis and recalling that the rate is being pumped at a rate of 
, Â 
so, just divide the Volume by the Rate given since they are under the same units: 
.
