When the toy train was completely submerged in a cuboid-shaped water tank whose two sides of the bottom is 44 centimeters (cm) and 35 centimeters (cm), respectively, the height of the water increased by 7 centimeters (cm). And then the toy car was completely submerged, which increased the height of the water by 3 centimeters (cm). Find the sum of the volumes of the toy train and the car in cubic centimeters (cm3).
