Explanation of answer?

What impulse is acting on the object if the force of 23 N is applied for .45(s) ?

I multiplied force by time and got 10.35 kg* m/s

The book says that the answer is 10 kg*m/s.
Can someone explain to me how this answer is right and not 10.35?

As you know,

$\tt Impulse(J)=Force(F)\times Time(T)$
Force given is 23N and time of impact is 0.45s. Plug in the values,

$\tt J=23\times 0.45=?$

I get 10.35. The book says 10 is the answer, why?
