Answer
$F= 1.2688\times10^{6}lb$
Work Step by Step
Pressure generated by the printing press $P=8.0\times10^{4}lb/in^2$
size of 20 dollar bill is given as length $l=6.1in$ and width $W=2.6in$
area of the bill $A=lW$
$A=6.1in\times2.6in$
$A=15.86in^2$
since $P=\frac{F}{A}$
so $F=PA$
so force generated by intaglio presses $F= 8.0\times10^{4}lb/in^2\times15.86in^2$
$F= 126.88\times10^{4}lb$
$F= 1.2688\times10^{6}lb$
