Measure the volume of a potato using a cuboid with a length of 10 cm, a width of 5 cm, and a height of 20 cm and a cylinder with a base area of 60 cm**2 and a height of 20 cm. It is known that the water level in the two containers is 10 cm high, and the water level rises by 2 cm when the potatoes are placed in the cylindrical container, how much will the water level rise when the potatoes are placed in the cuboid container?
用一个长10cm、宽5cm、高20cm的长方体与一个底面积是60cm**2，高20cm的圆柱测量一个马铃薯的体积．已知这两个容器中都现有水10cm高，把马铃薯放在圆柱体容器中水位升高2cm，那么把马铃薯放在长方体容器中水位会上升多高？
