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.
a. How wide is the gap between tiles in centimeters?
b. How wide is the gap in inches
c. How many algae-thicknesses is the gap between tiles
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?
