If you have 18 feet of ribbon and you want to cut the ribbon every 12 inches which is a foot. You will have 18 twelve inch pieces. if I am understanding your question correctly. Eighteen feet would equal 18 one foot pieces.
1 piece = 2 foot x 5 foot = 10 square feet 33 pieces x 10 square feet = 330 square feet 330 square feet x 0.30 = 99.00
3/4 of a foot = 9 inches 30 feet = 360 inches 360/9 = 40 pieces of ribbon
9 pieces: 6 yards = 18 feet, then divide by 2 feet per piece to get 9 pieces.
x= trees shadow t= height of tree itself 2/3T=X
A 30 foot circle covers about 707 square feet. 23 pieces would technically cover that. I'd get 30 of them so I wouldn't have to cut any of them.
The equation would be: number of pieces = total length of yarn / length of each piece. In this case, the equation would be: number of pieces = 4 feet / 13 feet. Simplifying, the equation becomes: number of pieces = 4/13.
1 foot = 12 inches so 12 feet = 12*12 = 144 inches from which 14 10" pieces can be cut.
It is 80 you stupid===============================Another contributor observed:The first answer to this question comes from a contributor who is not onlyoffensive in his attitude, but wrong in his math as well.The question doesn't say "5 square foot pieces". It says "5 foot square pieces".From that terminology, we understand that each piece is a square, with 5-foot sidesand an area of 25 square feet.It takes (400/25) = 16 of these pieces to cover an area of 400 square feet.
Simple Mathematics buddy.... 1 foot = 4 one fourth peices, so 6.5 feet = 4 * 6.5 = 26 So your answer is 26 peices.
Since 12" x 12" tile are 1 square foot, 50 of them would be 50 square feet.
