Omission error:

The cork is a sphere.

Maybe that will be of some help. Thanks again.

Sorry.

2x³ - 6x² + 1.92 = 0

x ≅ -0.52, 2.88, 0.64

-0.52 is an extraneous solution, so x = 2.88 inches or 0.64 inches

Cork is less dense than water, so it cannot be completely submerged.

Since the diameter of the cork is 2 inches, x ≤ 2 inches. Therefore, x = 0.64 inches.
