Question

A company specializing in pool conservation uses a product for water treatment whose technical specifications suggest that 1, 5 ml_ of this product be added for every 1 000 L of pool water. This company was hired to take care of a rectangular pool of constant depth equal to 1.7 m, with width and length equal to 3 m and 5 m, respectively. The level of the water blade of this pool is kept 50 cm from the pool edge. The amount of this product, in milliliter, which should be added to this pool to meet its technical specifications is 11.25. B 27.00. C 28.80. D 32.25. And 49.50.

Answer 1

To calculate the amount of the product needed, we need to find the volume of the pool. The volume of a rectangular pool is given by length x width x depth. In this case, the volume is 3m x 5m x 1.7m = 25.5 cubic meters. Since 1 cubic meter is equal to 1000 liters, the pool has 25,500 liters of water. According to the technical specifications, we need to add 1.5 ml for every 1000 liters of water. So, for 25,500 liters, we need to add 38.25 ml of the product. Therefore, the correct answer is not among the given options.
