Using the formula above, let's bring this all together. Example: You have a wall on your house that is 10 feet tall by 10 feet wide.(10' x 10') What is the square footage of this wall? Answer: 10' x 10' = 100 ft2 (100 ft2 = 100 SqFt = 100 sq.ft. = 100 Ext. SqFt) Now if a product costs $1.50 psf (per square foot) and you need 100 sq.ft. your cost would be $150.00.xample: You have a wall on your house that is 10 feet tall by 10 feet wide.
