A pizza parlor uses square prisms for their pizza boxes. Due to the crust rising, the height of their boxes is always 2 inches. Additionally, the volume of the pizza box must be 450 cubic inches to fit their standard-sized pizza. A worker determined that the equation 2x2 = 450 could be used to find the side length, x, of the box needed to reach that volume. Determine which statement is true about the solutions to the equation.
