Okay. A California King mattress measures 84" x 72" x 10" deep. That equals 60,480 square inches. Divide that by the number of inches in a square foot (1728) and you get 35 square feet. The formula looks like this: 84 x 72 x 10 = 60,480. 12 x 12 x 12 = 1728 (inches in one square foot). 60,480 / 1728 = 35 square feet. And, by the way, since fresh water weighs 62.4 pounds per square foot, the fulled Cal King weighs 35 x 62.4 = 2,184lbs.
