You are a driver of a dump truck with a trailer (dump bin) that is 21 feet long, 8 feet wide, and 6 feet tall. Daily, you haul full loads of dirt from one location to another. The dump bin can hold dirt equivalent to 1.2 times its capacity.What is the minimum number of trips needed to haul 20,000 cubic feet of dirt?

Explanation

The dump bin’s volume is 21 × 8 × 6 = 1,008 cubic feet. At 1.2 times its capacity, each full load carries 1,209.6 cubic feet of dirt. Since 20,000 ÷ 1,209.6 is about 16.53, you need to round up to 17 trips; 16 trips would not carry enough.
