A rectangular swimming pool is 46 ft wide by 75 ft long. The table gives depths (d) from x = 0 at the shallow end to the diving end. Use the Trapezoid Rule with n = 15 to estimate the volume of the pool, V = x 75 46 0 46.d(x) dx. 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 d(x) 4.4 6.6 7.6 8.3 8.9 9.4 9.9 10.3 10.7 11.1 11.5 11.8 12.1 12.5 12.8 13.1 The volume of the pool is 3450 ft3.
