How many gallons of water in a pool 35X90 that is 3 ft deep?

Answer 1

Answer1000 gallons is way off. The formula for acquiring the number of gallons a pool contains is the following: 1) Multiply the length x width (in this case 35w x 90length = 3150 square foot. 2) Figure out the average depth by adding the deep end and the shallow end together (ex. what is the depth in the shallowest end and what is the depth in the deepest end). If it is a rectangle pool it's easy to figure (in this case you gave the depth at 3 ft., I will assume that is 3 ft. all the way around) 3) After adding the deep end with the shallow end divide by two. This gives you the "average" depth of the pool as a whole (once again, in this case the only number you've given is 3. If the whole pool is 3 ft. deep then the average depth is 3 ft. deep) 4) Now, multiply the square footage with the average depth (in this case, 3150 x 3 = 9450. 5) You then multiply that number by the constant of 7.5 (in this case 9450 x 7.5 give you 70,875 gallons of water)

Your answer to how many gallons of water are in a 35 x 90 foot pool is 70,875.

Answer 2

By using the word "diameter", the question implies that the pool is perfectly circular, and the water in it takes a perfectly cylindrical volume, so these are assumed below. 1 gallon = 231 in3 The volume of water is (pi) x R2 x H = (pi) x (15)2 x 4 = 2827.44 ft3 = 4,885,804.8 in3 Water in the pool = 4(pi) x (15)2 x (12)3 / 231 = 21,150 and 2/3 gallons (rounded)
