Last winter, a water pipe with an inner diameter of 0.8 decimeters in the school was frozen and cracked, resulting in a large amount of water loss. It is understood that the water velocity in the water pipe is about 50 meters per minute. Do the math, how many liters of water will be wasted if the pipe cannot be repaired in 10 minutes?
去年冬天，学校的一根内直径为0.8分米的自来水管被冻裂，导致大量水流失．据了解，水管内的水流速度约为每分钟50米．算算看，如果10分钟还不能修好水管，将会浪费多少升水？
