493
+327
7+3=1(0) carry the one on the 9
1+9+2=1(2) carry the 1 on the 8
1+4+3=(8)
820
So the actually surface area can be split up by dif parts....meaning
2 side is 2.7*3.2*2 = 17.28
2 side is 3.2*2.1*2 = 13.44
2 sides is 2.1*2.7*2= 11.34
then u add up the areas = 42.06ft^2
then u look for what is the clossest...and that is 42gt^2
7a^2b + 10a^2b^2 + 14a^2b^3 =
a^2b (7 + 10b + 14b^2) <==
Answer: 5
