at what rate is water pouring into a rectangular bathtub with base 23sq ft
lb=23
volume of rectangle, v=lbh
v=23h
differentiate with respect to time
dv/dt=23 dh/dt.....equation(1)
the water level rises at a rate of 1.4ft/min
dh/dt=1.4ft/min
substitute in equation(1)
dv/dt=23(1.4)
dv/dt=32.2
At 32.2 rate is water pouring into a rectangular bathtub with base 23sq ft if the water level rises at a rate of 1.4ft/min
