To convert feet to inches, you multiply by 12 because there are 12 inches in a foot. So, 3 feet is equal to 36 inches (3 feet x 12 inches/foot = 36 inches). Therefore, 12 inches multiplied by 3 feet is equal to 12 inches x 3 = 36 inches x 12 = 432 inches.
There are 144 sq inches in a square foot. Doing the math gives an answer of 1,296 square inches.
1 square foot = (12 x 12) = 144 square inches 3 square feet = 432 square inches
Conver to feet (1/3 foot x 1/3 foot), then multiply.
Approximately 215.63 square feet.
3 x 30 = 90 square feet. 1 square foot = 144 square inches (12 x 12) So 90 square feet = 12,960 square inches
A foot contains 12 inches. Therefore, 6 inches is half a foot and 8 inches is 2/3 foot. (2/3)(1/2) = 1/3 square foot.
3 feet times 3 feet = 9 square feet
22feet 9inches
One feet is equal to 12 inches. Hence 6 feet by 3 feet is 216 square inches.
To calculate the area in square feet for a rectangle measuring 72 inches by 36 inches, you first convert the dimensions to feet. There are 12 inches in a foot, so 72 inches is 6 feet and 36 inches is 3 feet. The area is then calculated as 6 feet × 3 feet, which equals 18 square feet.
Approximately 4.083 square feet.
