A board foot is one square foot by one inch thick or 4 quarters (4/4). If you were using something thicker, then the square footage provided would be proportionately less. I.e. 8/4 lumber would yield half the square footage but would be twice as thick (2"). So, using 4/4 lumber would mean 2000 board feet for the house assuming no waste.
40 square feet. Multiply length by width to get square feet.
You say 12'x12 `—> that ' is the sign for feet. so if the patio is 12 feet by 12 feet then it is 144 square feet. You don't say what measurement the "4 thick" is, but I presume it is inches. 4 inches is 1/3 of a foot, so divide the square footage by 3 and that will give you the cubic footage - if the patio is 12 feet by 12 feet and 4 inches thick then the cubic footage is 48.
To calculate the square footage, we need everything in feet or in inches. Since we are going to end in square feet, it is easiest to convert everything to feet first. 7 inches is equal to 7/12 feet, since there are 12 inches in a foot. 4 feet and 7 inches is equal to 4 and 7/12 feet, or 55/12 feet if you make it into an improper fraction. Then you simply multiply 7/12 and 55/12 together to get the square footage, which would be 385/12 feet, or 32 feet and 1 inch.
It is: 24*4 = 96 square feet
40inch = 3.33 foot 48 inch = 4 foot so 4 x 4 x 3.33 = 53.328 or 53 and a third cubic feet - as you have three measurements it needs to be in cubic feet either that or the pallet square footage is based only on 40 x 48 3.33 x 4 = 13.32 square feet
