The question reads: "A swimming pool is 15.0 m wide, 24.0 m long, 1.00 m deep at one end, and 2.60 m deep at the other end. How many cubic meters of water can it hold? (The slope on the bottom is constant."
I tried solving it by turning one of the polygonal sides into a right triangle with a 1.60 m leg (2.60 - 1.00) and a hypotenuse of 24 and a rectangle with area 24 (24.0 m x 1.00 m), added up the total area, and multiplied it by the width of the pool. Does that make sense?
