How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon. But the world is messier than a textbook. Scientists in the Harvard John A.

The density of the stone is 7 g/\(cm^3\). The volume of larger irregular objects can be measured using a displacement can. Fill the displacement can until the water is level with the bottom of the ...

Objects with a higher density feel heavier ... measure the sides and multiply length by width by height: To find the volume of an irregular object that cannot be measured with a ruler, use a ...

How does one go about finding the volume of irregular shapes? One way would be to fill the vase with much smaller objects of a known volume. Then you could add up the smaller volumes to get an ...
