Answer:
1326 cm²
Step-by-step explanation:
1) Identify the equation of the surface area of a rectangular prism

2) Input the corresponding values
;
; and
into the equation, and solve for the area

3) ∴ 
Add 5 to both sides
5-5+x/3=5-11
0+x/3=-6
x/3=-6
times both sides by 3
3x/3=-18
x=-18
The range of sin(x) is [-1,1].
No matter what the value of x,pi,pi/2,pi/4,pi/6,-pi/2,etc the value of sinx will always be between -1 and 1(both included)
