Sealing a Gym Floor A gymnasium floor has an area of 2400 square yards. Each gallon of floor sealant covers an area of 350 square feet. How many gallons of sealant are needed to cover the gymnasium floor?
should the equation be set as 2400 sq. yards = 7200 sq. feet
7200 sq ft. / 350 sq ft = 20.5
answer; 21 gallons of floor sealant to cover 2400 sq. yards
there are 9 square feet in a square yard, not 3
so 2400(9)/350 = 61.7
they need 62 gallons
To find the number of gallons of sealant needed to cover the gymnasium floor, follow these steps:
1. Convert the area of the gymnasium floor from square yards to square feet. Since 1 yard is equal to 3 feet, 2400 square yards is equal to 2400 * 3 * 3 = 21600 square feet.
2. Divide the area of the gymnasium floor by the coverage area of each gallon of floor sealant. In this case, each gallon covers 350 square feet. So, divide 21600 square feet by 350 square feet to get 61.7142857.
3. Since you can't have a fraction of a gallon, round up the result to the nearest whole number. In this case, round up 61.7142857 to 62.
Therefore, you would need 62 gallons of floor sealant to cover the gymnasium floor.
