amilapsn · Answer

UV can't be 6ft. It should be between 2 and 4

anonymous · Answer

amilapsn · Answer

yes it's 3. but how did you get that...?

anonymous · Answer

well its the only number between 2 and 4.

amilapsn · Answer

why not 3.5 or something?

anonymous · Answer

well im not sure what formula to use for it but the reason i was saying 3 is because they are both whole numbers and the only in between number is 3.

anonymous · Answer

if it were 2.5 and 4.5 i would say it would be 3.5
