Answer:
Amount of paper needed to cover the entire box is:
360 in²
Step-by-step explanation:
Amount of paper needed to cover the entire box
= Total surface area of the box
= Total surface area of the cuboid
=2(l×b+b×h+h×l)
where l is the length of box
h is the height of the box
and b is the width of the box
Here, l=18 in.
b=6 in.
and h=3 in.
Amount of paper required to wrap the box
=2(18×6+18×3+6×3) in²
= 360 in²
