Understand that the average adult human body contains about 5 liters of blood.
Recall the conversion factor between liters and cups: 1 liter is approximately equal to 4.22675 cups.
Set up the conversion calculation to find the number of cups of blood by multiplying the total liters of blood by the conversion factor: \(5 \text{ liters} \times 4.22675 \frac{\text{cups}}{\text{liter}}\).
Perform the multiplication to find the approximate number of cups of blood in the body.
Compare the calculated value to the given options to identify the closest estimate.
