Question

the density of water is 1.00 g/mL. if your swimming pool holds 208,000 gallons of water, what is the weight of water in a filled swimming pool on tons?

Answer 1

I would convert density of 1.00 g/mL to lbs/cu ft. I believe that is 62.5 lb/s cubit feet.
Convert 208,000 gallons to cubic ft. There are 231 cu ft in a gallon.
mass = volume x density. You know volume in cu ft, you know density in lb/cu ft, solve for mass in lbs. Then convert to tons. Post your work if you get stuck.

Answer 2

868 tons
