3361 . 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?

A. 7.5 inches
B. 3 ft. 9 inches
C. 3 ft. 7.5 inches
D. 7 fit. 6 inches

View Answer	Favorite Question

Answer: Option B

Explanation:

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
