 A cubic foot of water weighs about 62.5 pounds. If an aquarium is 18 feet long, 10 feet deep, and 12 feet wide, what’s the approximate pounds-per-square-inch pressure (psi) on the bottom of the tank?
Definition
 You can determine the pressure of all that water by multiplying the volume of the aquarium by the weight of the water. Volume = lwh. The bottom of the tank is 18 feet long by 12 feet wide by 10 feet high for a total volume of 2,160 cubic feet (18 × 12 × 10). A cubic foot of water weighs approximately 62.5 pounds. 2,160 × 62.5 gives an approximate pressure on the bottom of the tank of about 135,000 pounds over the entire surface area. The surface area of the bottom of the tank is length × width. 216 inches (18 feet × 12) × 144 inches (12 feet × 12) = 31,104. Dividing the pressure of 135,000 by the number of square inches of surface area gives an approximate PSI of 4.
