Then multiply that number by the number of skirts to find the total material used on the skirts: 48 square feet / skirt * 3 skirts = 144 square feet. Then find the total amount of material she uses for the sleeves: 5 square feet / sleeve * 2 sleeves = 10 square feet. Then add the amount of material she uses for each part of the dress to find the total amount of material: 10 square feet + 144 square feet + 2 square feet = 156 square feet. Then multiply the total amount of material by the cost per square foot to find the total cost: 156 square feet * $3 / square foot = $468. The answer: 468.
