29. The rectangular tank given below is 50cm by 40cm by 20cm and is filled with water. (W=50cm H=20cm L=40cm) . Find the volume of the water (in cm) the tank. b). How many litres of water can the hold when it is full?

volume = l×w×h

v= 40cm×50cm×20cm

v=40,000cm³

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
