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 centimeters by 30 centimeters and is filled with water to a depth of 20 centimeters. The object sinks to the bottom, and the water level goes up 0.25 centimeters. What is the volume, in cubic centimeters, of the object?
The amount of water is 40 x 30 x 20, which is 24,000. It goes up by 0.25, so add 0.25 to 20 and rework it. 40 x 30 x 20.25 = 24,300 That is 300 more than without the object. So, the object is 300 cm³ in volume. Hope this helps!
