An Olympic-sized swimming pool of uniform depth measures 50 meters by 21 meters. The bottom of the pool is to be treated with a
sealer, and one gallon of the sealer covers 300 square feet of surface. How many gallons of sealer will be required for the job? Round to the nearest whole gallon.
The bottom of the pool is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = Length × width
Olympic-sized swimming pool of uniform depth measures 50 meters by 21 meters. The area of the bottom would be
Area = 50 × 21 = 1050 m²
The bottom of the pool is to be treated with a sealer, and one gallon of the sealer covers 300 square feet of surface. This means that the number of gallons of sealer required for the job would be
1050/300 = 3.5gallons Approximately 4 gallons to the nearest gallon
