Judis father is 6 feet tall. The minimum height to ride a roller coaster is given in inches. How many inches tall is Judy's father?

We are asked to convert Judy's father's height in inches since the given measurement in the problem is in feet. We know that 1 foot is equivalent to 12 inches.

Solving the height in inches, we have:

height = 6 feet * (12 inches / 1 foot)

height = 72 inches

The answer is 72 inches.
