**My answer is off by 10^-2!**

## Homework Statement

An air-filled capacitor consists of two parallel plates, each with an area of 7.60cm^2 and separated by a distance of 1.8mm. If a 20 V potential difference is applied to these plates, calculate the capacitance.

## Homework Equations

[tex]C=\epsilon_{0}\frac{A}{d}[/tex]

## The Attempt at a Solution

[tex]C=\epsilon_{0}\frac{A}{d}[/tex]

[tex]=(8.85*10^-12)\frac{0.076m^2}{0.0018m}[/tex]

=3.74*10^-10F

Book answer: 3.74*10^-12? What am I doing wrong? thanks.
