Our ancestors invented the method of water leakage timekeeping as early as 700 BC. The students in the science and technology group also tried to make a cuboid water leakage timer. This timer is 4dm long, 2dm wide, and 3dm high. Hour. One day at 12:00 noon, the students filled the water leak timer with water. When school ends at 5:00 pm, how many liters of water are there in the water leak timer?
我们的祖先早在公元前700多年就发明了用水漏计时的方法，科技小组的同学也尝试做了一个长方体水漏计时器，这个计时器长4dm，宽2dm，高3dm，全部漏完要8小时．某天中午12时，同学们往水漏计时器里加满了水，下午5时放学时，水漏计时器里大约还有多少升水？
