10 ft X 10 ft square tank will hold 1000 cubic feet of water or 7480.51 gallons 10 ft round tank will hold 785 cubic feet of water or 5872.207 gallons
Given that this stands out a mile as almost certainly a school homework question, to answer directly would be to make me complicit in cheating. So I will tell you how to calculate it, which would appear to be the point of the question: 1) The relationship between depth and pressure of water is linear. 2) If water X ft deep exerts a pressure of P lb/in2, then water of Y ft deep will obviously exert a pressure of P(Y/X) lbs/in2 Given thats information you can now solve the original question.
An aquarium is 10 ft long, 3 ft wide, and is filled with water to a depth of 7 ft. Water weighs 62.4 pounds per cubic foot. What is the volume and weight of the water in the tank
This is a really fiendish problem, but we may have outsmarted it.Ordinarily, the dimensions of the pool wouldn't matter, because the pressure onlydepends on the depth of the water ... you always find the same pressure at thesame depth below the surface, whether you're in a pond, a lake, a bathtub, anocean, or a swimming pool. So our first instinct was to calculate the pressure at6-ft down, since your pool is 6-ft deep.But wait! Why is the quantity of water given ? Could it be that the pool is notcompletely full and sloshing over the rim ?Volume of the full pool = (12 x 30 x 6) = 2,160 cubic feet = 16,157.9 gallons.Ah hah! The pool is not full!Those 11,500 gallons fill it to only (11,500/16,157.9) x (6-ft) = 4.2704 feet. (rounded)The pressure under 4.2704-ft of water is 1.841 psi(rounded)(Using 5 psi = 11.6 ft of water, which we found somewhere on the www.)
10 * 10 = 100 square feet!
