4
20
-36
Answer:
6 ft
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2
216 = 6s^2
Divide each side by 6
216/6 = 6s^2/6
36 = s^2
Take the square root of each side
sqrt(36) = sqrt(s^2)
6 =s
Each side is 6ft
Well your going to need 5, since 4 wouldn't be enough, 4 would only be 24.
B for 8 would be 6.2
b for 9 would be 7
The b is adding 0.8 each time
Hope this helps!
