To measure the volume of an irregular rock specimen, the students of the experimental elementary school first poured 1 liter of water into a cuboid water tank, and measured the water surface to be 8 cm high. Please use what you have learned to calculate the volume of rock specimens?
要测量一块不规则岩石标本的体积，实验小学的同学先将1升水注入一个长方体水箱，测得水面高8厘米，然后将岩石标本完全浸没在水中，这时水面高9.6厘米．请你利用已学知识计算岩石标本的体积？
