                                A jumbo hopper barge is basically a rectangular prism used to transport bulk items on the river systems of this country. It is 100 feet long, 30 feet wide, and 14 feet deep. They can only be loaded to a depth of 12 feet since there has to be some percentage of the barge above the water. 
What is the volume of the prism that can be filled with water?
