We’re asked to** determine the minimum number of cubic nanocontainers** that a

For this problem, we need to do the following steps:

*Step1. Determine the volume of 1 nanocontainer. *

Recall that the equation for finding the **volume of a cube** is given by:

$\overline{){\mathbf{V}}{\mathbf{=}}{{\mathbf{l}}}^{{\mathbf{3}}}}$

where *l =** edge length *

*Step 2. Determine oxygen, O _{2} requirement per hour in the bloodstream for a person. *

A **human being** uses about 550 liters of pure oxygen or **19 ft ^{3} (cubic feet) per day**.

*Step 3. Determine minimum # of nanocontainers that will supply the oxygen needed per hour *

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. One potential application of nanotechnology is the construction of artificial cells. The simplest cells would probably mimic red blood cells, the bodys oxygen transporters. For example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a persons bloodstream. If the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. Suppose that the nanocontainers were cubic and had an edge length of 24 nanometers.

What is the minimum number of nanocontainers that a person would need in their bloodstream to provide 1 hours worth of oxygen?
