Here are the essential concepts you must grasp in order to answer the question correctly.
White Blood Cell Concentration
White blood cell concentration refers to the number of white blood cells (WBCs) present in a specific volume of blood, typically measured in cells per cubic millimeter (cells/mm^3). In this context, a normal concentration is approximately 12,000 cells/mm^3, which serves as a baseline for calculating the total number of WBCs in a given volume of blood.

Volume of Blood
The volume of blood in an adult human is generally estimated to be around 5 liters. This volume is crucial for determining the total number of white blood cells, as it provides the necessary context for scaling the concentration of WBCs from a per-unit volume to the entire blood volume.

Scientific Notation
Scientific notation is a method of expressing numbers that are too large or too small in a compact form, using powers of ten. It is written in the format 'a × 10^n', where 'a' is a number greater than or equal to 1 and less than 10, and 'n' is an integer. This notation is particularly useful in scientific contexts for simplifying calculations and clearly presenting large quantities, such as the total number of white blood cells.
