The shelves must be at least 15 centimeters or 6 inches above the floor.

Hopefully this helps :)

Answer 2

Answer:

The correct answer is:  6 inches.

Explanation:

Having shelves at least 6 inches above the floor allows cleaning food establishments to be easier. Given the situation that an object drops down and rolls under the shelve, it will be easier to take out without risk that someone's arm or hand will get stuck. It also prevents insects to form plagues since they usually do not take place in wide ventilated spaces.
