Your heart beeps at the rate of 70 beats per minute. Each beat pumps about 60cm^3 of fluid against a blood pressure of 120mmHg. How much expansion work (in Joules) does the heart do in a day?

Your heart beats at the rate of 70 times a minute; each beat pumps about 60 cm3 of fluid against a blood pressure of 120 mm Hg. How much expansion work (in Joules) does the heart do in a day? (Note: the heart actually does much more work than this. The heart muscles are contracting, the blood is accelerated, and there are frictional losses and other factors involved.)
