A recipe for crispy rice treats results in a mixture that fills a 9-inch by 13-inch pan to a depth of one inch. If a crispy rice treats mixture resulting from 1.5 times the original recipe is poured into a pan that is 10 inches by 15 inches, to what depth, in inches, will the pan be filled? Express your answer as a decimal to the nearest hundredth.

The volume  of the mixture filling the original pan is

 

9 * 13 * 1   =   117 in^3

 

1. 5 times this volume   =   175.5 in^3

 

So

 

175.5  =  10 * 15   *  depth

 

175.5 = 150 * depth     divide both sides  by 150

 

175.5 / 150  = depth  = 1.17 in

 

 

cool cool cool
