Final answer:
To convert square feet to square inches, multiply the number of square feet (140) by the number of square inches in one square foot (144) to get the answer, which is 20,160 square inches. The options provided in the question do not include the correct answer.
Step-by-step explanation:
To convert 140 square feet into square inches, we first need to know how many square inches are in one square foot. There are 12 inches in a foot, so to find the number of square inches in one square foot, we multiply 12 inches by 12 inches, which equals 144 square inches.
Next, we multiply the total square footage by the number of square inches in one square foot to get the conversion:
- 140 square feet x 144 square inches/square foot = 20,160 square inches.
