<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 />
2. Definition of supplementary angles
I’m not too good with proofs but hopefully at least one answer helped lol sorry
£350 because 420/6 is 70 and 70*5 is 350
140 you divide 490 by 3.5.
The answer is 16.25 adding all of those up
