volume of tank=length*width*depth
And volume given=3*6 cu ft.
hence length*width*depth=3*6 cu ft
4*(1/2*4)*depth=3*6 cu ft
depth=(3*6)/ 4*(1/2*4) ft
depth =2.25 ft

As it is given that tank will fill in 6 mins. and water is at the rate of 3 cubic ft per min. means in 6 min 18 cubic ft water is in the tank and tank will be filled. so volume of tank is 18 cubic ft.

thus we have length=4ft
width=2ft

and volume is
4*2*Y=18

and thus
y=2.25(depth)

This is the answer
