Dear Vikrant,
I hope you doing well.
The minimum required height for Uttar Pradesh Police male is 168 cm for UR/OBC/SC candidate however there is some relaxation for ST candidate and for ST it is 160 cm only.
Now as you have mentioned your height is 5.6 inches then if we try to convert minimum height that is required for UP Police in inches then 168 cm will 5.5118. As you can see your height is more than the minimum required then you are eligible for this post.
I will suggest you check yourself by searching calculators on google that convert centimetre in inches and like these.
I hope this information helps you.
All the very best!!
