To find the thickness of a fingernail, we need to add the thickness of a human hair (4 * 10^-3 inches) to the additional thickness of a fingernail (0.011 inches).
So, the total thickness of a fingernail is 4 * 10^-3 inches + 0.011 inches.
Adding these values, we get 0.015 inches.
Therefore, the thickness of a fingernail is 0.015 inches when written as a decimal to 3 places.
