Textbook Question

Chapter 4.3, Problem 18P

Imagine that you are standing on a sandy beach, like the one in Figure 4.26, gazing off into the distance. How many grains of sand might you be looking at? To solve this problem, make reasonable assumptions about how wide the beach is and how far down the length of the beach you can see. Make a reasonable assumption about how many grains of sand are in a very small piece of beach, and explain why your assumption is reasonable. Based on your assumptions, make a calculation that will give you a fairly good estimate of the number of grains of sand that you can see. Explain your reasoning.
