Cardiac output is calculated as the product of heart rate (HR) and stroke volume (SV), where stroke volume is the difference between end-diastolic volume (EDV) and end-systolic volume (ESV). Here, SV = 130 ml - 40 ml = 90 ml. Therefore, cardiac output = HR * SV = 125 beats/minute * 90 ml/beat = 11,250 ml/min.
