Volume = (l * w * h) or (11 * 3 * x) which will equal surface area. Volume is 33x for now
Surface Area = 2 (x * 11) + 2 (x * 3) + 2 (11 * 3)
Set Volume equal to surface area. I simplified SA already.
33x = 22x + 6x + 66
33x - 28x = 66
5x = 66
x = 66/5 or 13.2
36/27=1.3
7x1.3=9.1
The actual length is 9.1meters
Its C)126in I think because top base is 16, bottom base is 12 and the height is 9.
4x^2+4x-8=0
X^2+x-2=0
(X+2)(x-1)=0
X= -2 or 1
