## Homework Statement

a. How wide is the gap between tiles in centimeters?The tiles are 2 thumbnail-thicknesses apart. A thumbnail has a thickness of about 0.90 mm. An inch is exactly 2.54 centimeters. One algae cell is 9.45 micrometers across.

b. How wide is the gap in inches

c. How many algae-thicknesses is the gap between tiles

## Homework Equations

## The Attempt at a Solution

First off, I just want to know if I did a and b correctly. To set up a, I took 0.90 mm x 2 to get 1.8 mm per gap. I then converted 1.8 millimeters in order to get to centimeters. I came up with 0.18 centimeters. For b, I just divided 0.18cm/2.54cm to get the answer in inches. As for c, I suppose I will just convert, what do you think about a and b so far?
