To find the thickness of a fingernail, we need to add the diameter of a hair to the thickness of a fingernail.
The diameter of a hair is about 4 × 10^(-3) inches, so we can write this number as 0.004 inches.
Adding this to the thickness of a fingernail, which is about 0.011 inches, we get:
0.004 + 0.011 = 0.015 inches
Therefore, the thickness of a fingernail is 0.015 inches.
