Answer :
Final answer:
The mass of the water in the swimming pool, given its volume of 185 cubic yards and the density of water of 1 g/cm³, is approximately 311,578 pounds. This result is not among the provided options.
Explanation:
The question asks for the mass of the water in a swimming pool in pounds, given the volume in cubic yards and the density of water. We first need to convert the volume from cubic yards to cubic centimeters, as the density is given in grams per cubic centimeter (g/cm³). There are 764554.858 cubic centimeters in a cubic yard, so 185 cubic yards is 185 * 764554.858 = 141342149.73 cubic centimeters.
Since the density of water is 1 g/cm³, the mass of the water in the pool is also 141342149.73 grams. However, the mass needs to be in pounds. Using the conversion factor of 0.00220462 pounds per gram, the mass of the water in the pool is 141342149.73 * 0.00220462 = 311577.671 pounds, which is approximately 311,578 pounds, therefore the answer is not among the options provided.
