Number 15 is the only function on the page because a function is when even input has a different output. so 2 numbers can’t be equal to the same output. 14 is the only one that fits that description. 13 implies that’s it’s not a function bc there are only 3 outputs (1,2, or 3) and there are 4 inputs meaning that every input will not have a different output making it not a function

Step-by-step explanation:
To know how much paper he needs, we need to find the surface area of the box he wants to mail and thats the amount of paper.
Surface area of cuboidal box:
= 2( lh+bh+lb)
where l is length
b is breadth
h is height
= 2( 5*3+8*3+5*8)
= 2 ( 15+24+40)
= 2*79
= 158 inch^2 of paper
