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?
<span>The volume of the object equals the volume of water the item is displaced. That volume of that would be 40 cm by 30 cm by 0.25 cm = 300 cm^3</span>
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!
