Denise bought some lace to sew around 3 square pillows. Each pillow measured 4 incheson each side. How many feet of lace did denise need for all 3 sides?
I think you meant all 3 pillows.
4 inches times 4 sides = 16 inches
then 16 inches time 3 pillow = 48 inches
Those are mighty small pillows!
The perimeter of one pillow is 4 * 4 = 16 inches.
3 * 16 = 48 inches = ______ feet
maybe they are doll pillows, or maybe just pin cushions ...
To find out how many feet of lace Denise needed for all three sides, we need to calculate the total perimeter of the three square pillows.
The formula for the perimeter of a square is P = 4s, where P is the perimeter and s is the length of one side. Since all the pillows have the same side length, we can use this formula to find the perimeter of one pillow and then multiply it by three to get the total perimeter for all three pillows.
Given that each pillow has a side length of 4 inches, the perimeter of one pillow would be P = 4 * 4 = 16 inches.
Now, we need to convert the length from inches to feet, as the required answer is in feet. Since there are 12 inches in 1 foot, we can divide 16 inches by 12 to get the length in feet.
16 inches / 12 = 1.33 feet (rounded to two decimal places)
So, the length of lace needed for one side of each pillow is approximately 1.33 feet.
To find the total length needed for all three pillows, we multiply the length needed for one side by 3.
1.33 feet * 3 = 4 feet (rounded to two decimal places)
Therefore, Denise would need approximately 4 feet of lace for all three sides of the square pillows.
