<span>Old Surface Area = 202 ft^2
New Surface Area = 1818 ft^2
Notice we have this ratio:
(new area)/(old area) = 1818/202 = 9
and how 3^2 = 9. This is no coincidence.
The old surface area is multiplied by 3^2 = 9 to get the new surface area
.
If you asked "What would the surface area of the prism be if each dimension were quadrupled?"
, then you would multiply the old surface area by 4^2 = 16 to get the new surface area So really thats how you would solve that </span><span />
I think it is a I think so idk I’m not that good at math
You already know that since you need to pay 10$ for the room you would do 75-10 and you have 65$ left. 12 goes into 65 5 times, because 12x5=60. You then have 5 dollars left. So Carrie can invite 5 people to her birthday party.
I believe the answer is 249.
