Question 1187361
The human body contains approx. 30 trillion red blood cells.  If these cells were placed tightly  together, they would fit into a cube approx. 5 in. on each edge.  

1) Determine outside surface of cube in sq. yds.
The surface area is 6s^2 = 6*25 sq inches.
1 yard = 36 inches
======================

2)If the outside surface of cube was divided into 30 trillion pieces, determine outside surface in sq. yds.
-----------------
There's no inside surface area, so what does "outside surface area" mean?
Divide the SA by 30,000,000,000,000.
