Water has been poured into an empty rectangular tank at the rate of 5 cubic feet per minute for 6 minutes. The length of the tank is 4 feet and the width is one half of the length. How deep is the water in the tank? Correct Answer 3 ft. 9 inches

6 minute ধরে 5 cubic feet = 5*6 = 30 cubic feet in tank length = 4ft, then width = 4/2 = 2ft therefore, base area = 4*2 = 8 sq ft base area*depth = 8*depth = 30 cubic ft depth = 30/8 = 3.75 feet = 3 ft 9 inches
