Answer:
No, his answer doesn't make sense
Explanation:
Well, first we know that centimeters are smaller than inches, so it wouldn't make sense to say that 5 is more than 10. Furthermore explaining it, 25.4 cm is equivalent to 10 inches. So, no, his answer does not make sense.
I'm not sure if this made too much sense, if it didn't, I can try again to explain it a little better
