    approximately 8,566 gallons

    One cubic foot of water weighs 62.42796 pounds.

    One gallon of water weighs 8.345404 pounds.

    In your example, (I’m assuming it’s a round pool);

    Figure how many cubic feet in the pool (pi r squared times depth), multiply by the weight of a cubic foot, divide by the weight of a gallon.

    3.141592654 (pi) X 9 (radius) X 9 (radius) X 4.5 (depth) X 62.42796 / 8.345404 = 8566.02… gallons (approximately)
