An engineer is determining the amount of pressure that water from a lake is placing on a drainage wall using the formula P=(2)-1wh2, where P is the pressure in pounds per foot, w is the unit weight of water in pounds per cubic foot, and h is the height of the water, in feet.

Use the equation shown to determine the pressure, P, on a drainage wall, in pounds per foot, when the height of the water is 3 feet and the weight of the water is 48.6 pounds per cubic foot.

P=(2)-1(48.6)(3)2

218.7 pounds per foot.
