last one promise

in this question ALL of the answers should be given IN STANDARD FORM TO ONE DECIMAL PLACE.

a) 1mcubed blood is estimated to contain 5*10(this 5*10 has a little 12 near the 10) white blood cells. how many white bloody cells are there in 1litre of blood.

b) during the operation a patient loses 750cm cubed of blood. using figures you have obtained in part a above, estimate how many white blood cells are lost.

c) the heart beats on average about 72 times per minute. on each beat it pumps out about 75g of blood. how many kilograms of blood does the heart pump out each day?

A liter is a cube shape with each side 10cm, or 100mm, or 1/10th of a meter.  Hope that helps.
