The fuel tanks for airplanes are in the wings, cross section below. The tank must hold 5400 lb of fuel with density 42 Ib/fts. Estimate the length of the tank using Simpson's Rule. '2 33 YA y'S Horizontal spacing = 1.6 ft yo = 1.4 ft, y1 = 1.5 ft, y2 = 1.8 ft, y3 = 2 ft, y4 = 2.1 ft, y5 = 2.4 ft, y6 = 2.2 ft The length of the tank is |ft. (Round to the nearest tenth as needed.)
