Volume of a rectangular prism = Length * Width * Height
Volume of the rectangular prism =
Length of the prism = 18cm
Width of the prism = 11cm
We need to find the Height of the Prism,

Answer:
x = 3 and 7
There are two true solutions.
Step-by-step explanation:
To solve , use inverse operations by squaring both sides of the equal sign.
The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.
(x - 3) ( x - 7) = 0
x-3 = 0 so x=3
x-7 = 0 so x=7
Now check each solution into the original equation to be sure it solve the solution and is not extraneous.
