If Judy wants to fill a rectangular pool with water, approximately how many cubic feet of water will she need if the pool’s dimensions are 10 feet wide by 12 feet long by 5 feet deep?


The key words in this problem are volume and rectangular. As soon as you see these words, you should know just what to do. The volume of a rectangular solid is \(\text { length } \times \text { width } \times \text { depth }\). In this case, that means \(12 \times 10 \times 5=600\). The correct answer is (B).
