Answer:
The surface area of the large box is 2 times larger than that of the small box.
Step-by-step explanation:
Okay so using the given 6s (formula for the surface area), let's plug in the side length of the large box first.
6(6) = 36
Now let's do the side length of the small box next.
6(3)=18
We can now do 36/18 to figure out how many times larger the large box is when compared to the small box.
36/18=2
Answer: the surface area of the large box is 2 times larger than the small box.
