A problem by Diana Ir
You can find the volume of an irregularly shaped solid object by completely submerging it in water and calculating the volume of water the object displaces. You completely submerge a solid object in a rectangular tank that has a base 40 cm by 30 cm and is filled with water to a depth of 20 cm. The object sinks to the bottom, and the water level goes up 0.25 cm. What is the volume, in cubic cm, of the object?
