What is the square footage of a 3'0" x 6'8" door?

To find the square footage of a door measuring 3'0" by 6'8", you first convert the dimensions into feet. The width is 3 feet, and the height can be converted from inches to feet. Since there are 12 inches in a foot, 6'8" translates to 6 + 8/12, or 6 + 0.6667, which equals approximately 6.67 feet.

Next, multiply the width by the height to determine the area:

Width (3 ft) x Height (6.67 ft) = 20.01 sq ft.

Thus, the calculation confirms that the area of the door is indeed approximately 20.01 square feet, making the answer correct.
