The current in a conductor is expressed as $\displaystyle \mathrm{I}=3 \mathrm{t}^2+4 \mathrm{t}^3$, where I is in Ampere and t is in second. The amount of electric charge that flows through a section of the conductor during $\displaystyle \mathrm{t}=1 \mathrm{~s}$ to $\displaystyle \mathrm{t}=2 \mathrm{~s}$ is $\displaystyle \_\_\_\_$ C.
