※ 引述《alonefish (小花仔~)》之铭言：
: A red blood cell has a 120-day life span.if an average adult has 5 L(5000cm3)
: of blood and each cubic millimeter contains 5 million RBCs,how many new cells
: must be produced each second to replace the entire RBC population?
: 答案是 2400000 可是不知道怎麽算 >0< 请大大帮忙
5000L X1000(cm3换算成mm3) X5000000 /120 /24(一天24小时) /3600(一小
时3600秒) = 2411265
