Have you ever heard of "the tip of the iceberg"? The tip of the iceberg is only a small part exposed on the water surface, and most of it is hidden under the water surface. If the volume of an iceberg exposed to the water is about 80 cubic meters, this "tip" only accounts for (1/7) of the iceberg, then What is the volume of this iceberg in cubic meters?
你听说过"冰山一角"吗？冰山一角露在水面上的只是一小部分，大部分隐藏在水面下，如果一座冰山露在水面上体积约是80立方米，这"一角"只占这座冰山的(1/7)，那么这座冰山的体积是多少立方米？
