You can find how much the blood pumped by multiplying the heart rate with the stroke volume. The heart beats by 72 beats per minute with 70ml blood pumped per beats. Then, the number of blood pumped would be:

number of blood: heart rate * stroke volume = 72 beats/min * 70ml/beats * 60min/hour * 1liters/1000ml = 302.4 L / hour
